We are new to chickens... we had a coop already on our property but it was empty inside. My husband built a roosting rack that he put on a elevated wood platform... trying to figure out what to put down on the wood platform to help with poop clean up -- was thinking the big oil pans - but they are not long enough. The platform itself is 5 feet long by 36 inches deep. Also looked at the trays you put under washing machines -- but they are an inch too wide!!! I want something I can take out to empty and wash. My only other idea was a tarp flat on the wood. Any ideas?
