I've never had this problem, but we have lately been getting a lot of rain. I throw my grass clippings into the run and my 20 hens love picking and digging in them. With all the rain the clippings have seemingly aided in water retention in the run and turned it to a swamp. They free range for a good part of the afternoon but seem unhappy when in the run. Has anyone had this problem? Is there anything I can do short of shoveling about 8" of composted grass out of the run? Thanks in advance.
