I will post to keep this at the top of the list.
My current dilemma is about if I want to brood from day 1 outside in walk in coop, or if I want to use the play pen inside my rec room for a few weeks. I will be using a heat plate and could easily make a draft guard out of some cardboard....so the coop could work. Temps will be "low", but most likely not freezing. Way less messy outside, but then again it means the chicks are further from the humans and it takes more effort to go out to check on them/hang with them.
Could brood them inside the house in the rec room for a while, but it would be stinkier and messier. Although they would be down with our stinky dog, so the smell is already not the best down there. Brooded quail down there before and it wasn't THAT bad of a smell.
Decisions, decisions.
