Last month I had a broody hen (Runty) who took fabulously to 5 little day old chicks. Now I have another ( Little Twin) which I put in a smaller pen, gave her 2 new chicks and she pecked at them. I took the chicks away and let her out into the yard. She went back into the main coop and got back on her nest. I then opened the back of the coop and put the chicks under her. So far she hasn't done anything. What is the chance she will accept them?
