I’ve got a hen hatching 6 fertilized eggs we bought and put under her while she was broody. This our first time hatching eggs and one has begun hatching. The head and most of its body have been out about 3 hours but nothing much has progressed since then. Still lying next to the mama hen with shell on its butt, peeping but not moving around a whole lot. Is this normal? It has begun to dry a little now but has not yet fully come out of the shell. And how long does it normally take chick to fully hatch once it’s halfway out like that?
