I have a small coop for my four hens, but I just adopted 6 chicks that someone bought for a photo-shoot and then didn't want. I also have over 30 free range muscovy ducks (all rescue). I was planning on building an 8x8 coop with a roughly 350 square foot run to keep them all contained. I also planned on have a lean to duck shelter away from the coop as the ducks prefer to sleep outside anyway. I'm on a budget but want to do this right. I was thinking of either building on deck blocks which are sort of expensive, or laying a thick layer of stone down and putting my treated 2x8s directly on that. The stone would be cheaper as I have plenty extra laying around already, but I think deck blocks would help prevent moisture getting to the wood. For the run I planned on framing it with treated 2x4s but was concerned about ground contact over the course of several years. Also with the ducks I regularly dump their water troughs & kiddie pool and that is a lot of water that could be coming in contact with the 2x4s regularly. Anyone have any suggestions on this? Any thoughts, suggestions, or money saving tips would be greatly appreciated!
