Ok we are all ready to build our own coop and have the blue prints for it and ready to go. We know how it will look and what size. I was wondering if I could have some tips on what materials to use on the floor? What wood works best for coops in cold climates? And any other helpful hints and tips. We had a store bought coop last year and all our chickens did great so now we are upgrading our chicken amount, so we need to upgrade our chicken coop. Any tips help.
