Terrible hatch rates

[cloudstreaker]

Yeah, it helps ensure some eggs don't get stuck in a cooler/hotter spot the whole time. I move mine from the outside in and vice a versa.

That's extremely interesting! It's amazing how hard it is to incubate and the mama hen just sits on them and they pretty much all hatch. I really hope one of mine goes broody so I don't have to go through this hassle lol. With my luck, the whole bunch of them will go broody at the same time!

The late hatches are almost surely telling you your temps are to low. They're not developing like they should, or at the rate they should. The longer they are in the incubator, the tougher the membrane gets, and the tougher the shell gets. Therefore, making it harder for them pip. Both internally and externally. An additional calibrated thermometer or two inside the incubator should help you know the correct temperature. Alot of time the built in thermometers on the incubators are inaccurate. I have better hatch rates with my temperature at 100.5. If your incubator temperature is set at 99.5, chances are its cooler, and chances are its even cooler than the ambient temperature inside the eggs. Your humidity isnt no where near as important as correct temperature. I have better hatch rates with dry hatches. Here in missouri in in my house, running dry keeps the humidity around 35%, depending on weather and season. But yes, as someone mentioned before, the room the incubator is in, the rooms temperature will affect the incubator temperature. Its recommended to keep the incubator in a room where the temperature stays at a certain consistent temperature, and away from drafybareas and direct sunlight.

Mama hen will roll her eggs around. I have 3 hens sitting right now and prolly hatch 1 last run which make 6 hatches.
You will get the hatching down just practice. Everytime you hatch pick up something from the experience and learn.

To start off humidity while incubating shouldn't go above 30%.

in mine, the humidity always ranges from 40 to 80 during the whole incubation+hatching period and we have the best hatch rates
