I recently purchased a house built in 1900 and the entire property is basically compacted clay; the property is graded properly for living in a city, meaning the rainwater flows from the front away from the house to the lowest spot on the property which is the very back of the backyard, close to the property line that butts up against the property behind me. I have a small back yard and am limited as to where I can place my chicken coop and run. As I mentioned, the soil is compacted clay, it has standing water all fall, though out the freeze/thaw cycle in the winter and all spring. Although the standing water will eventually dissipate, the soil never really drys out, it's always damp and frequently soggy. The area tends to be fairly shady due to the huge, old maple and oak trees in my neighbors' yards as well as a huge maple in my own yard, but it does receive some sun throughout the morning and early afternoon. I started amending the soil last year by putting down 4 in thick of wood chips, knowing they will eventually break down and add organic matter to the soil, but wood chips are about amending the soil, not soaking up water and my biggest concern is what I should use for the floor of the chicken's run, which is basically 25ft x 40 ft. I want to keep the run dry because, as we all know, wet chicken poo stinks, it's not good for the chickens to be in constant muddy conditions and no one wants to be slogging through muddy chicken poo, least of all my chickens. I know using chopped up straw, hemp and wood shavings will help, but with the amount of water that area gets in the spring, fall and through out the freeze/thaw winter cycle it won't really dry out even if I put in a 12 in deep layer of it. Realistically this is the only place I can put the coop and run since I have a small yard. Does anyone have any suggestions on what I can do or use to prevent the run from being in a continually damp, if not wet state?
