We have 13 adults hens in a large room in our barn with a run. We also have 17 five-week old's. Some are feathered beautifully and others not so much. Right now the babies are living in the bathroom tub and have recently discovered they can fly I am splitting the room in the barn with chicken wire so the girls (and one boy) can get used to each other. The total size is probably about 10 x 15-17 and I'm taking one end about 10 x 5 for the babies. Because it's still so cold here at night (40) I'm putting in a heat lamp. Where is the best place to put this so no one gets hurt by it. I thought of putting it in the adult side shining into the babies but I'm worried about curiousity and burned chickens. Thanks.
