So the multi-level coop I just build has some drainage issues in the run. It did fine at first but then we got some seriously heavy rain and it hasn't been the same in a couple weeks. It does sit in a low spot of the yard but unfortunately I cannot change that. Prior to the rain I added pea pebbles from home depot but they scratch so much that the dirt got mixed right in! So much for the easy cleanup of all their waste! I have seen some people suggest using all river stone, or sand but I'm not sure how much this will help. I can only build up a little and I would like to keep cleaning poo up an easy task. I will probably have to remove some earth from inside the run since it is starting to smell rather bad. All ideas or thoughts are welcomed!
