I'm debating a location to put a brooder or 2 and wanted to get some opinions. Brooders are plywood and I can make them as sealed as need be. I just put up a couple of those carports that you probably see everywhere and I closed the sidewalls and one of the end walls to the ground and will build large swinging doors for the other end but it will have a gap at the top and below. Its basically an uninsulated tin shed with swinging doors. With no drafts and heat lamps in the brooder, does this sound feasible?
