You could use a wooden shed easily for now, especially in your climate, because you could take one of the man-door frames, replace the filler boards with hardware cloth and have plenty of light & ventilation immediately (you could do the top halves of two doors instead). Then put in a table (functions as poop board) with a roost on a couple of small blocks fastened to the top. Stack milk crates for nest boxes under the table or on the side. Just an idea, I read a couple of articles or a thread or two here on BYC about renovating a Rubbermaid double-wall shed this way. Wood is better protection against chewing predators though.I know. Very pricy, which is why I am hesitant. I think a nice wood shed could work, but we’d have to install windows and ventilation. Hubby is a contractor and has the skill to build something beautiful. But he doesn’t want to and something quick, as long as it’s big enough and nice enough, would alleviate some moving stress.
