I have not had a hen go broody in the winter where I have let her hatch eggs. I had an abundance of eggs and decided to let her sit on 10 while I stuffed my incubator as well. My question is about the babies...should I let her keep her babies with her or pull them and put them under heat lamps in a broody box. It hasn't been too cold yet, but we are in Wisconsin and it can get darn chilly on some winter nights. The eggs hatching from the incubator will be going in the broody box.
