I had no idea there was so much to learn about raising chickens. I am very impressed with the wealth of knowledge being shared here on BYC. I am in the middle of modifying a 24' camper into a coop for about 30 to 40 chickens. I will be ordering my chicks in the next week or two. I am very excited to but a little nervous that I will do something wrong lol. I can already see I will be spending a lot of time here.
Have you checked out the Coop section? Many people have used odd things as a coop, off hand I can think of a school bus, trailer, car, huge storage units, packing crates etc. You might put "Camper COOP" in the search box and see what comes up.
