So a week ago I introduced 5 7 week old chicks to my group of girls. The alpha hen was fine with them so everyone else was to. But yesterday my alpha hen suddenly passed away, so now the 2 girls vying to be leader are relentlessly chasing the chicks to the point where I might have to put them back in the brooder. But they are to big for it now. What do I do? None of my hens are laying yet the older group is around 5 months old.
