I did my first egg hatching with a broody hen. I had my white silkie sit on 4 eggs. 2 of them never developed, one of them hatched 3 days ago and the second chick hatched this evening. She sat on the 2nd chicks egg the whole time, until it came out. I just found it cold and lifeless in the nest and she was sitting away from it with her other chick. What went wrong? I stuck the baby back under her, hoping if she can warm it up, it might be ok. But not sure if it'll work.
