The homemade brand!!! lol I took a medium sized cooler and googled how to convert it into a incubator. I've used it for hatches and so has my sister and it has worked great! I just went and checked it and its back to normal! I think that hubby had turned down the heater and that may have caused it to drop due to our cooler weather right now. But i made sure i let him know not to turn it down and let me do it from now own "i'm hatching babies dear!" lol We put a window in the top sealed it and took a lamp set and put that in the bottom next to two pans for water and put a computer fan (w/ a blue light so i can see in even when the light goes out!

) and used a hot water heater thermastat to turn the light on and off for temp control. My sister and i have both had 80% hatches with chickens and quail in it. I have another incubator thats a styrafoam one i made but it goes way off when the weather changes! This one only changes by a degree or two. Hence why i added a heater to my room to keep the temp normal! These old country homes don't always have consistant temps throughout the house

But i think i got it figured out and i hope i dont have any problems with it. ( if i even get really addicted i have about 3 more BIG coolers i could easily get away with converting... lol but mine will hold 15 chicken eggs comfortable and probably 40 quail so i am good

)

Sounds neat. I am not that savy so I am using the Brinsea I bought last year. This is my first hatch with it and it is holding steady so far.

I will eventually get myself a brinsea since i have heard so much about them! But at the time i had almost all the things at hand to make an incubator so i went on and did it and it has worked great so far! I will have to post some pictures sometime! My sister is going to borrow my other one and hatch some of my quail eggs to show her little girl how it all "works" lol Got the whole family into the chickens... my mom was talking about converting her laundry room to her hatchery haha and my moms not an animal person

I have been using my Hova Bator Forced Air with a brass waffer themostat for 7 years now. It never temp. spikes regardless of room temperature and I don't have humidity problems as long as i follow the instructions for the trays. It also holds 68 eggs at one time, but i've gotten about 100 quail eggs in their at once with room to spare.

I love my Hova Botor!

Wow...Now that my brain is buzzing with humidity issues and calibrating.

Sure am glad I have a Brinsea. I really don't have to doing anything. I add water every 3rd day, and candle when I get the urge. I don't even take the eggs out, I candle them right in their spot.. So speaking of candling. I order shipped eggs first time ever, they came last Sat. Set them Sat. night and 7/8 are developing.

I was so so nervous, especially after all the craziness during the NY Hatch.
I am following along with this hatch, so good luck everyone...

Congrats Ms.FufftButts.

I could be wrong but I think most people are using their humidity calculation numbers incorrectly. Take Wolftracks' calibration yesterday that read 68 when it should have been 75. I think most everyone is subtracting the 68 from 75 to get the difference and then adding that number, 7 in this case, to whatever reading they see later... ie reading 23 plus 7 must be 30%

However, this is not the correct way to adjust your readings. What you need to do is divide 75 by your reading when calibrating... 75 divided by 68 equals 1.102941 (I would round to 1.10) then when you are looking at your reading later ie 23 you multiply by this number to get a true reading.. 23 times 1.10 equasl 25.4%.

The only time the actual difference is 7 is when the meter reads 68. When it reads lower than 68 the difference is much less than 7 and when it reads higher than 68, the difference would be more than 7. For example if it reads 10 it is actually 11, and if it reads 85 the actual would be 94.

Hope this helps!

No, this is confusing to me.

Let me try to explain this again... When we calibrate a hygrometer, we are looking for the magic 75% which is what it should read when it's in the bag with the cup of saturated salt water. If it only reads 68% it isn't 7% off, it's 10% off (the percentage difference between 75 and 68). Since we are already dealing with a percentage, we can't just subtract the 68 from the 75 to figure the amount that it is off.

This means that if the base line or starting point is 75% we have to figure the percentage difference from our reading and the baseline of 75% and multiply that number against future readings to see what the actual humidity is. For example:

If our calibration reading is: divided into 75% Calibration multiplier is
68% 75% divided by 68% 1.10
65% 75% divided by 65% 1.15
60% 75% divided by 60% 1.25

this means that
If our calibration reading is: during the hatch we see the actual humidity is
68% 20% 20 times 1.10 equals 22%
68% 40% 40 times 1.10 equals 44%
68% 55% 55 times 1.10 equals 60.5%
68% 68% 68 times 1.10 equals 75%

60% 20% 20 times 1.25 equals 25%
60% 40% 40 times 1.25 equals 50%
60% 55% 55 times 1.25 equals 68.75%
60% 60% 60 times 1.25 equals 75%

Does that help any??

HUH????

If it doesn't have $$$$ in front of it I can't figure it out.

I have a confession to make. I scored really high on my SATs back in the day, but I got a LOT of lucky quessses in math! See this is why I needed Bill for this. He explained all that to me once and I said "huh" and he told me not to worry about it and he'd watch it for me. I guess he can't take care of it from where he is or it would be spot on.

I have a huge issue here. I decided that I was going to run two bators and use the one that holds best. Calibrated 3 hygrometers and using 2.

The first was the 68% reading. I have it in the first bator. My temps dropped this morning to 78 and humidity is 70! I haven't even added water. so I'm playing with it. ugggg

The 2nd one calibrated to 71% I have it in bator 2 and the temp dropped to 75 and humidity is 59%.....Don't sure where my temps went, but I'm going to go buy a couple of good old fashioned themometers. I have some here, but I just don't trust them. And didn't put them in so I will now just in case.

My daughter is at the hospital for surgery and I can't get to her. I was waiting on some money to fix my car and this morning I think I've made the problem worse, so I'll be without a car. The money not coming and I need to change my head gaskets, so I have to go talk to my machanics and too affraid to bring the car back home. Gonna be a nice long walk back. My son is half way across town at school and I have no one to pick him up, so I will either be in here all day or not much at all. Every time I have plans something happens and I end up in a panic.

I'm waiting for one of these bators to stabilize so I can set the eggs and run, but I don't want to jeapordize this hatch.

And my TJs eggs are out since that's across town too.

OMG I need a life!

OK leaving for the shop. Looks like I'll be setting late. I don't want to mess this set up from the beginning and my temps are just coming up, but the humidty isn't dropping.
