I've got my "coop" (an extra large dog travel kennel) set up in the garage right now. I just got my hens (my first!) today and the breeder has been using a heat lamp with them in their outdoor coop. I don't have a heat lamp and don't want to buy one. Is it alright to keep them in the garage until the cold snap passes? I'm also worried about raccoons. I haven't had a chance to add a layer of hardware cloth to the coop yet and I'm scared to put the coop in the backyard at night without that extra reinforcement.
