We are waiting on a few chicks from broody hen, day 15... She so far is just sitting on her eggs in the nest boxes. I have a lot of QUESTIONS! Do i need to move her? Can the babies be with the other chickens (I have 25 hens and 1 roo) Should I raise them or let her? Also, the nest box is about 2-3 ft off the floor. Is she too high? Thanks!
