Thank you so much for providing information! It honestly has been a great incubator other than humidity control, which I agree with you 100% the direction for 100ml of water is way too high! It would be at 90% with that! But I am wanting to try your idea of taping the hygrometer on the wall to allow it to stay in that I purchased separately. I stopped my hatch at day 25 but I really feel it had passed on and checked with water Candling and it was wanting to float. I am going to try my next batch with non shipped eggs to check the success rate and have comparison. I used a straw to get water in through the hole but tubing would be easier! Thank you again for your input but I feel for the the price this incubator is an amazing thing.

With the janoel 12 incubator even when I am adding a couple MLS of water it continues to spike humidity for an hour two then will drastically drop. Have you experienced this?

i've had mine running with eggs in it for the last week and a half. I candled the eggs at 7 days and there are live chicks. :)

I do have to adjust the temp down slightly on warmer days and back up to 38 when it's colder. The ambient temp here seems to make a big difference on the internal temp of the incubator. I found that putting water in the bottom kept the humidity way too high , so I found a small cup and keep water in it. I'm keeping the humidity around 35-45 for incubating. I'll increase it for hatching.
How did you increase the humidity?

Hello, I have been reading a little about the Janoel 12 incubator and have looked online for better instructions, as the one included in the box for us english speaking people is incomprehensible, to put it nicely. And I am an American, so my english isn't proper english anyway!
I am very good at interpreting what people whose native tongue is not english are trying to say in english, I have lived abroad and traveled all over the world but some of these instructions have even me baffled. So, let me do a simple quick run through for how to get it set up and going.
Hatching shipped eggs: Let them sit pointed end down in an egg carton for 24 hours at room temp, in the room you will have the incubator running in. because you don't know the breeder as well as yourself, don't know cleanliness, if they cleaned off the poo before shipping to you, if there is some still on there, etc. you need to sanitize your eggs before putting them in your incubator. If you see any brown spots or streaks on the egg, wipe it off gently with a dry piece of material, dish rag, paper towel, etc. then, get out some purified bottled water- I use this for my wash solution and rinse water. I use Brinsea brand Incubation disinfectant concentrate, and follow the directions on the bottle EXCEPT- I make sure the water temp of the wash solution is 100* F, and then I rinse them off with 100* F of the bottled water. Wash your hands first! After sanitizing and rinsing them, I let them set on a paper towel and dry at room temp, then I load them in the incubator. Any time I touch the eggs after this, I wash my hands first. I dont candle my eggs until the 18 day when I remove the turner, and I only toss eggs with a blood ring. All others except the blood rings go back in. I also wait for approx. 26-28 days until I remove any unhatched eggs. Late bloomers are ALWAYS hatching out and suprising me, every time.
For the Janoel 12:
I use this one for a small clutch I want to hatch, or any expensive or rare important eggs I want a good hatching success with, or any eggs which I cant tell which end is the pointy end- which happens a lot with my younger araucanas for some reason. Reason being is that in a stand up incubator, you have to put the pointy end down, and if it is not then you are essentially putting them in upside down and preventing the hatch. Again, I don't candle my eggs until day 18, so I don't look for air sacs, etc. In the Janoel 12, the eggs are laid on their sides and rolled around slowly and gently in the automatic turner, much more like they would be naturally under a hen. When you open the box, you will have two different white trays, one with stands and one with two raised bars running along the sides, no stands. Place the one with the stands to the side, this is the one you will put in the incubator later for hatching. For the first 18 days you will be using the one with the two raised lines on the sides. Put the egg tray inside of the raised lines, so it can slide back and forth. put two of the dividers inside of the egg tray, spaced evenly. This is so you can put 3 eggs inside each lane, for a total of 9 chicken eggs- it will not turn 12 chicken eggs properly because they are too close together to move and roll like they are supposed to, only put 9 in there. Do not try putting two on the outside and hand turning them, this will break them trust me. It is hard to tell if it is turning them or not, if you are new to this, and you have to make sure the metal rod that is sticking out of the round plastic circle is inserted inside the rectangular handle on the side of the egg tray EVERY TIME YOU PUT THE LID BACK ON or it will not turn the eggs. Mark your eggs with an X on one side, and an O on the other if you are concerned it is not turning them- then you will see that it actually is, so long as that metal rod is in the hole of the egg tray handle. If the turner is not working, or if it stops working, you will then have to turn them by hand 3 times a day yourself. The temperature is not always perfectly accurate, so I keep two medical grade mercury thermometers sitting on top of the eggs to keep an accurate temp- excessive, yes I know but the temp is the most important thing, humidity can fluctuate.
I don't set the low and high parameters on this incubator, never have. I've heard too many people losing chicks when they do this. I simply see what my medical thermometers say, and adjust the temp on the incubator up or down until the medical thermometers read right at 37.5 C or 99.5 F. Then I leave the machines temp adjustments alone, for the entire time. It adjusts and keeps it where I set it just fine. But, of course I have my thermometers inside the whole time, sitting on top of my eggs and check them any time I open the incubator to add water, etc. just to make sure the incubator is doing its job right. I also wrap a bath towel around the outside of the entire incubator- dont cover the top, just the sides. This helps the incubator keep temp accurate without burning out the motor from constant on and off. Dont ever cover the airhole in the top- the eggs need this little oxygen to help them incubate properly.
For humidity, I have a good hygrometer I put inside to check the humidity with. It is a small round one, and I tape it inside on the end where it wont interfere with the tray movement, so that I can see my humidity through the clear plastic without having to open the incubator every time. I keep the humidity between 40-55% the first 18 days. Then, for the last few days during hatching (lockdown) I put it at 65% by adding tiny bits more water. I don't go higher than 65, because when the eggs start cracking open the humidity goes higher and sometimes really high if they all want to hatch at once. One thing I've learned with this incubator is that the instructions to put 100 ML of water in there is wrong- I usually only need to add approx. 15 ML when I first start it up, then maybe 5 ML every few days to keep it between 40-55%. I suppose if it is winter time and the air is very dry, or if you live in a very dry arid climate it may actually need the 100 ML of water, but you have to use a hygrometer to check the humidity on the inside of your incubator and adjust accordingly, don't go by what the instructions say, go by what your thermometer and hygrometer sitting inside the incubator says and add tiny bits of water until it is right. I have a syringe that I put a piece of fish aquarium tubing on the end of, and I insert the tubing through the airhole until it hits the bottom of the tray, then gently inject a little water. Dont drip water all over you eggs, and don't ever use cold water. Always use warm, clean (filtered) water. At day 18, I quickly open the lid, gently take out the eggs and lay them on a towel, and quickly candle them in a dark room. If I see any blood rings, I throw them out. Blood rings are easy to recognize, it's exactly what it says, a red blood ring around the inside of the egg. This is bacteria involved, and these can explode inside the incubator due to being a dead egg and growing bacteria inside which the high temps are perfect breeding ground for bacteria. Throw these out. I take the tray with the two raised sides that the egg tray has been sitting in the last 18 days out of the incubator and put in the tray with the stands (peg legs on bottom). I add about 10 ML of water to the bottom of the incubator and I have a piece of rubber/foam shelf liner I have cut to fit inside the incubator, and clipped off 1/4 of it from the end, so the moisture on the bottom can still rise up and keep it humid inside without being blocked by the rubber pad. The pad is for the baby chicks after they hatch, to keep the other eggs from being rolled around too much by little chicks jumping all over them, and to keep baby chicks from getting splayed legs (deformed legs) from the slippery plastic floor, and for easy clean up when I'm done. I gently lay the eggs down on their sides, spaced evenly apart so they have room to roll around and hatch without bumping into each other, then I put the lid back on. I check to make sure the humidity is at 65% and add tiny bits of water through the airhole with my tube if I need to until it is at the right humidity for hatching. I never open the lid after this. At 19-22 days there is activity, you may hear peeping, you may see little holes, you may see rocking and rolling, cracked lines along the side of egg- you may see a chick come out and lay there like its dead for a long time- resist the urge to open, don't open it. The peeping from one chick encourages the other chicks to hatch out and join it- so don't remove it even if it's fluffy and adorable and staring at you with those cute little birdy eyes through the plastic- leave it with its little buddies. If you feel it is too crowded, and 3 or more are really rolling the unhatched ones around in there, take a few fluffy, fully dry energetic jumpers out quickly, put the lid back on in a hurry but leave one in there to peep and encourage the others to come out. another thing to note is that the humidity will rise a lot when eggs start hatching out, because of the moisture released during hatching, so don't stress about adding water and getting it up to say 75%, trust me it will rise a lot during hatching, you will see. I wait a full 28 days before I am done with a hatch. I've had chicks hatch at 26 days a lot. Maybe because they were kicked around a bit by the other chicks, I dont know but I always have one or two late ones, so be patient and don't count all your eggs before they've hatched.

Good luck! I hope this helps better understand the hatching process, the Janoel 12 incubator and how to use it, and maybe a few little tricks and things you can do to get a better hatch rate
May I ask what kind of medical thermometer and what kind of hygrometer you use? I bought a hygrometer/thermometer combo on Amazon and I’m worried it’s not accurate or my incubator is not accurate. It is the Janoel 12 also.

I have had my Janoel 12 for a few years now. I live in Australia. A very hot part of Australia. Well at least from mid-spring, through summer and into mid-autumn. I just want to make people aware of a few issues this incubator has. Particularly if you live in a hot climate like Australia. Firstly humidity. When following the instructions (100ml) it WILL give you an average of 65% Relative humidity. Because this is all about Surface are and not the quantity of water, you will be able to maintain a lower humidity by using a small shallow dish in the bse of the Bator instead of filling the water on the floor. So a Plastic lid from a Metamucil (fiber for old people like me :p) container gives me ~50-55% RH. But yes, if I fill the floor with 100 ml of water I get between 60 and 70%.

The second issue is heat control. This unit has the transformer (power Supply) housed inside the Roof of the Incubator. This will be ok any many climates, but not where I live. If the Abient (Room Temp) is 32c or above then the Built-in Transformer and other electronics produce enough heat on there own to push the Incubator temperature above whatever you have it set at. Right now I am incubating Eclectus Parrot Eggs, but before that, we hatched many chicken eggs. However, we were constantly trying to monitor for "Over temp" Issues and having to turn the power off etc. Eventually, we purchased an Inkbird ITC-308 Temperature control Thermostat. Basically, the 240v power that we have here in Australia is fed to the Incubator via the inkbird Thermostat/Controller. I have dropped the Inkbirds Thermocouple (sensor) in through the top so it reads the internal temperature of the Incubator. That means that Anytime the Incubator Temperature Exceeds 37.1 it automatically cuts the power, untill the temperature drops to 36.7 and then it allows power to be restored to the incubator.

The other thing that's great about the inkbird Temp controller/thermostat is that it has a very loud alarm that can be configured for both high Alarms and Low Temp Alarms. It sounds somewhat like a smoke alarm. this alerts me to the fact that an "Over-Temp" Event has actually occured. (there is also a model that has WiFi for reporting and logging to your smartphone etc).

When an over-temp event occurs, I then switch on a 6 or 7 Inch Destop fan to blow on the top outside of the incubator lid. This seems to help disapate any excess heat. but be very careful about doing this. Because, when the Ambient room temperature again drops back to lower temps then the fan can cause so much heat loss that the poor, cheap and weak Janoel 12 can not make enough heat to combat the Desktop Fans Effects and then you have the opposite problem (not enough heat).

For e.g. One night, after a very hot day. I had a few glasses of wine and went to bed forgetting that I had employed the use of the fan. When I got up in the morning and checked on the Incubator, I found the Incubator was struggling to bring the temperature up past 30.0c So perhaps employ the use of a timer on the fan power.

To sum up I would say that in a sense and in some climates the Janoel 12 represents great value for money. but if you are a serious animal lover and losing your babies would cause you great distress and especially if you plan to hatch many eggs of one kind of or another over a long time I would suggest, nay implore you to consider a slightly larger investment and get something like the Borotto Lumia 8. That's what we are gearing up to buy.

One reason that we like the idea of the Lumia 8 is that it is a 12v model, which means the 240v to 12v Transformer will be placed outside of the Incubator, hopefully eliminating Over temp events. Unless, of course, the ambient temperature exceeds 37c. Where we live, we usually get at least 20 to 30 days of the year above 40c (outside) and some days we get as much as 49c. On those days it would be possible for the room temperature to exceed 37c. Although in that case, I would move (and do move) the Incubator into the bedroom where we have an Air conditioner. However, I am reluctant to do that as our bedroom is very noisy for a whole bunch of reasons, Our Pet Dogs also sleep in the room with us.

I have read elsewhere than in cold climates the Janoel 12 often has to be covered with a towel or other insulating material to assist it in maintaining temperature.

If you buy Janoel 12, it is very possible that you will have to do some tinkering of one kind or another to ensure success. After you purchase a fan, a quality thermostat, and maybe even have some failures, you might find yourself wishing you had been a little more generous with your spending (like we have found). Other than that, it's a great low budget way to get started in Incubating and Egg Hatching.

To be fair, you will read Posts and articles from many satisfied Janoel 12 Users. Just saying you should be aware of this if you live in a climate that is considered to be a hot climate or a cold climate.

Good luck and Happy Hatchings!
