My husband is building a coop for my two hens. The coop has to be in our lanai which has a two foot cement block wall and then the screen above that. The coop itself is 10'long, the roost is up above the run and the nest is then attached to the roost with a divider creating two nests.Now the dilemma!! What would you put on the floor of the run which is all plywood?? We are thinking of putting a few squares of grass sod on one end and the rest wood/pine shavings. However..I'm thinking of ease of cleaning as well as safety for my two hens!! Does anyone have any better ideas please?? I'm new to this site.. but am going to try to attach a picture of the coop in progress. Thanks!!
