Keep 'em coming! I have tons of lumber in the garage. I hope to make my brooder into a coop/tractor all by itself. It's currently just hardware cloth over a wooden frame (3x7) and about 4 feet tall inside the big girls' coop. I can't decide weather to make that the run part of the tractor and build a coop onto it or make that into the coop with some siding and insulation, then put the run on it. This would be for my older babies (4 wks and above). I'm going to make a smaller brooder inside the big girls' coop for any younger babies I have. The current one just takes up so much space in their house (5x10).
