Mine is a shed as well. I made a second story, took the 3 feet on each side and divided it up. The second story is about 3 feet high. I wish the one hen I have laying would lay on the second story instead of the first story. It would make life a lot easier.Luckily my dogs guard my chickens from everything. I had a raccoon snooping around and breaking hatching eggs from under my hens, but the dogs have pretty much nipped that problem. Sounds like you have a great set up. My set up is basically a shed halved and one side turned coop. I store the feed and bedding and supplies in the other side, but I'll soon have to expand into that side too. I have 8 phoenix chicks hatching as I type this. All my chickens currently free range during the day, but I've purchased fencing for a breeding run. I have the one roo to play with right now...just to work out the kinks of my thought process.
