Right now we have 6 hens and 2 roosters living in two tractors. The tractors work well, but I would like the chickens to have more room- so we are building a coop. Look on my BYC page to check out the coop in progress. So far we have used mostly recycled materials. We did have to buy the paint, hardware, and roofing. We still have to do doors, ramps, floor, and roosts. We also need to figure out how in the world we are going to do the yard. Any suggestions are welcome.
