My broody hen has been sitting on 6 eggs in her own "broody box" (large dog crate). Her first chick hatched early (yesterday) and is doing fine. One more hatched this afternoon. I got home just as it was hatching, and somehow the egg rolled out of her nest area before the chick got all the way out. The chick got out and made its way to the hen, and she started her "danger cluck" and attacking it. Do you think its because it didn't hatch under her? Do you think she might attack the rest of the chicks/ should I try to reintroduce the rejected chick later?
