...you put new chicks into a run with two adult hens? Would they kill the chicks? Would they sit on them to keep them warm? This is something I've always wondered. I'm not going to do it. I have a trusty brooding box I just bought for the chicks I'm getting in two weeks. I was just curious. What does it take to get a hen to brood chicks that aren't her own or that she didn't hatch?
