Heya, total newbie here with a question. I'm planning on having about 3 birds and am going to build a small, portable coop+pen-- a tractor basically but with the two parts separate for easier moving. The "house" part will be 3'x4' and about 2.5-3.5' tall inside, and as secure as I can make it: plywood, 2x4s and hardware cloth. If I can get a warming lamp into the coop, is there any reason why I can't put baby chicks right into their house instead of keeping them inside in a brooder for so many weeks and then moving them? Or is there anything I would need to do to temporarily convert the coop to a brooder? Between my cat and dog, there are more predators *inside* my house than outside!
