Hi, I have a broody hen. She has been sitting on eggs for 21 days. They have started hatching today. So far 2 have hatched. They are both very lifeless. Not moving at all. If I pick them up they chirp a little but the cant seem to pick up their heads so it just dangles. I have no idea why. I doubt they'll still be alive in the morning. What could be wrong? Will this happen to all the chicks that hatch. I am feeling very miserable about the whole situation. I will add that she is on a clutch of eggs from 5 different hens and 1 rooster. I have hatched eggs from these chickens in an incubator a fair bit and have never had a problem.
