I have a broody BO hen that I want to put some eggs under. She will be in my pole barn in a small dog house, no heat. Will she be able to keep eggs warm enough to hatch, and if she hatches them, can she keep the chicks warm enough without extra heat? Dec here can be anywhere from mid to high 30s, to mid to low teens. I could bring her into the basement, but I don't know if I want her and the chicks in the house for 3 months till it gets warm enough for them to go back outside. If she hatches the chicks, then I want to let her raise them, to me it would just be mean to take the babies away to be raised in the house and leave her out in the barn. Any ideas?
