I have a chick that's partially hatched and some eggs close to hatching that I had to take out of my broody pen----the hens whose eggs had hatched were trying to eat the other eggs/chicks when they started to pip. My question is, if I want to stick the new chicks under the remaining broody hen, do I do it as soon as they hatch-----even if it's one at a time----or do I wait until they're all hatched to do it?
