I have 4 broody hens separated from the rest of the flock. Two in one box and one in another to start. Got another broody hen, got sick of trying to oust her every day to get the eggs from under her. So i put her in with the three other broodys. She chose to join the two, making it three in one box, they shared the box for at least ten days to hatching. They hatched six or seven over several days. Then the trouble started today. They seemed upset and pecky at the babies. Found a newly hatched cooling chick outside the box they had pecked in the head. Removed it to a heated nest. Saw another newly hatched in the box but they were not keeping it warm. Removed that. Later I went in and found a chick with a big bloody injury to it's head. Removed that and removed another that looked unhappy outside the box and cooling. Help, what went wrong? Too many hens? The rest are ok for tonite, I hope. I have another broody hen that I kept moving aside. So tonite I isolated her, gave her fake eggs. Can I introduce the chicks to her tomorrow night? Two seemingly healthy and two somewhat injured? Has anyone had this problem?
