I am ordering 26 cornish x in the next two weeks. I am planning on building a 10x3x3 "coop" to fit into their kennel. I was wondering if I can put them in there from the beginning. I was not planning on letting them out until they are around 2-3 weeks old. Their kennel is 10x20' and I am planning on free ranging a couple hours a day too. Right now, the temps are around 70 during the day, and 50-60 at night. I was planning on putting two heat lamps in there right in the middle so the whole box gets even heat, but they can also get away from it. If I need to, I can insulate it a bit with Styrofoam. I really do not want them in my house, and my dogs and cats are not chick friendly.
