Today is day 22 for my cuckoo marans eggs. I've had some low temperature fluctuations due to my house being cooler this time of year. Well my first chick had trouble getting out of the shell. The top of the shell stuck to its head and it couldn't get free. I finally had to rescue it and put a few drops of warm water to get the shell unstuck. It has been out of the egg for a few hours and in the incubator, but never dried out. It still looked wet. It was laying on its back and moving, but never got up and walked around. So I opened the bator again. This time it is stuck to the top of another egg, and it's wing is stuck to it's head. So I carefully removed it, and dampened a warm paper towel and held it for a few minutes. It is all crusty and hard on the outside, not soft and fluffy. Anyways, it's not looking too good. Two other chicks are out of the shell and doing okay, and one more is pipped. Any thought about what's wrong with this chick and how to help it?
