Topic of the Week - Incubating eggs

Pics
I just got back to raising chickens again after a 3 year absence.
I have a 4250 Farm Innovator unit. Very sinple and efficient. I had one of the yellow Chinese units, and had trouble making it work. Even my daughter got it to working, but it didn't stay up to speed.
I am raising BLRW (Blue-laced-red- Wyandotte's). I like the size and color. Hopefully about 25-30 chicks. The shipping of eggs leaves a lot to be desired (USPS).
 
My most recent incubator tool is an uninterrupted power supply (UPS). The power grid in my area seems to be becoming rather worse in the past year. While I now have both a portable battery generator and a gas generator to deal with powering critical devices through full outages, I have the new problem of being plagued by little brownouts this spring. Frequent brownouts in past areas I've lived with crummy grids have killed more electronics for me over time than anything else; computer power supply units and chargers, lights, aquarium pumps, etc. Last thing I need is for my incubator to get toasted in a similar way. So, this year I plugged my incubator into a spare UPS I had sitting around to try to guard it against that kind of electrical abuse. Interestingly, that old and cheap UPS isn't able to run my satellite internet rig or any other substantial piece of electronics - so I felt like it was a big waste of money after I first got it and it's been sitting collecting dust for a while, but it apparently has quite sufficient juice for a Nurture Right 360. I have regularly been hearing the UPS click over to rely on its battery as the lights in the room are getting dim.
 
I’m going to be starting my first hatch process tomorrow after I pick up my last breed of chicken eggs. I’ve had my incubator running since yesterday (nurture right 360) and have a hygrometer/thermometer. Temp is between 99.5-100. Humidity is at about 50-55%.
Am I at a good spot number wise for humidity and temp? I know everyone has a different opinion but I’m terrified of drowning the chicks from too much humidity.
In my experience that humidity range has worked great for me. I’ve incubated chicks at 70% the whole incubation period due to a difficult incubator, and saw a much lower success rate at that high of humidity as opposed to the 50-55% range. You definitely want to get it to to the 70-75% range during lock down but in my opinion you should be good at that % until then.
 
I have a much higher success rate with dry hatch than with the high humidity. And yes, it is fully dry. When the chicks internally pip the humidity jumps. When they externally pip the humidity jumps, and when they hatch it skyrockets. Since the chicks provide their own humidity, I see no reason to do it artificially.

My incubator humidity has never dropped below 21%, and usually ranges between 25 and 30. Except during hatching, when it can briefly get as high as 80% but usually hangs around 50 to 60.
 
- Good incubator recommendations, especially for new hatchers.

I used HHD 12c incubator for around 6 years about once a year, maybe twice. However, this last year it made a pretty rough sound when it booted up. It worked fine, but the noise put me on edge so I've retired it. It controlled temperature, you had to add the water to the tray yourself and it was a little hard to access, and it self turned. For my very first incubator it was great! It worked pretty reliably and was fairly affordable. Its best for those who do maybe a small hatch once a year, or classroom hatches (what I used it for mostly).

Currently I have a Sailnovo 56c incubator and I enjoyed it so much I got another! I did a lot of digging for a new incubator that met my criteria and this was the one! It manages the temperature, it self turns, it tracks humidity and self waters, it stops turning during lockdown, and you can change the number of days which makes it viable to use for other species! I set the eggs in, put the lid back, and let it go. I like the hands off approach to it. There's also a water tray if one would prefer to use that! The lid is clear compared to the HHD so you can see in. For its size I think it's priced on the lower end. This will be my second year with it so we'll see if it holds up, but last year I put it though constant hatches (up to/around 6?) so it made it through constant use. If you want a larger incubator (that isn't a commercial fridge style) that handles all the stuff for you, I'd recommend this one.

- Homemade incubators.

I'm definitely not technically inclined to make a homemade incubator 😅 but kudos to those who do!

- Selecting eggs for incubating.

I start by culling (getting rid of) any dirty eggs. That means nothing with poop, dirt, cracked/cracks, egg matter like yolk etc, or really anything that sticks to the shell that is foreign. Then I look through and find the most Egg Shaped eggs. A chick is gonna grow inside so you don't want a golf ball, football, fairy egg, double yolker, etc. A good rule of thumb for me is to pick the most photogenic ones! You can candle the eggs (process of shining a light through the shell to see things inside) to see any cracks or fractures too.

- Humidity during incubation - "dry" incubation, what humidity do you incubate at, etc.

My incubator that I use keeps the humidity level throughout the incubation process (I can't remember what it is atm TvT but know that its whatever the Standard it) and then raises it at the end for hatching! (I don't do dry hatches so I can't speak on them!)

- How to handle power outages, temp spikes, and other incubation mishaps, like cracked eggs, etc.

Admittedly, I have no backup plan for if the power goes out. I'm grateful to live somewhere where if the power goes out it's usually for just a minutes, never longer than an hour.


Anything you'd like to add.

I think incubation can range from simple to rocket science. There's a lot of ways to do it, and so many little factors to think about. It can be extremely overwhelming for those who are just starting out. A little advice on that front is to take a deep breath and exhale. Eggs are surprisingly forgiving. I used to worry that my eggs were too cold or too hot or that they'd spontaneously combust and die. Or that I was opening the lid too much or not giving it enough humidity. I ran my first incubator for years without a humidity monitor! I still successfully hatched eggs. Temperature is a little more important, but I accidentally ran mine a few point degrees warm and was confused why my eggs kept hatching at twenty days! Incubating is a special experience I think, because you're facilitating the start of a life. Whether its your first hatch or your hundredth remember to enjoy it! <3
