Hi, we are still building our coop, hopefully to have it complete this weekend since the girls are way too big for their rabbit cage. THe area we are puttint he coop on is a 12 X 12 are that used to home ducks. Once the Ducks were gone my dad had broke up the concrete and added a ton of stones for drainage. We have leveled out the are as best as possible and added dirt. It has been packed dowa bit now just by use walking on it. Do I need to worry about the chickens digging up the stones and getting hurt? Should I add sand on top of it? The run is closed on the top and we plan on added a tarp or some kind of roof to help keep most of it dry but sooner or later I am sure it will get wet. Should I put hay or straw down? Also the neighbor's behind me have posion ivy that growns through my fense near where the coop/ run are going, is that danagerous for chickens?
