Cruiser, I love the mini coop. What are the dimensions?? I need to build (DH) a 4 by 6 coop for some columbian rock bantams I'm getting and want to make it on wheels. I am going to need big wheels and will have to build it as light as possible. I've been telling him it should be built with 2 by 2s and I want a plastic corrugated roof with hardware cloth underneath for safety. He says we have shingles (did our roof in 2006) and the extra plywood & shingles will be OK. Time will tell. Nice job!
