I saw another thread about flies in the coop but figured I would make my own since situations are different.. Haven't had any fly issues. But we just had a huge rain that turned my run to mud for days. I got in there a couple days ago and mucked it out and then set a box fan for the past couple days to air it out. Today I put the box fan away and this evening went out to give the girls some treats and there are TONS of flies in the run. Many around the food but they seem to be pretty spread around the entire run. I imagine the rain and moist ground has something to do wit it since we weren't having an issue before. What can I do about this? I can go out and rake again but don't think it will help. The run is just grass and dirt right now the girls haven't cleared the grass yet. I'm planning on putting out sand in the next few days to try to help the soggy mud pit the run turns into when it rains. Any ideas? I know there will be flies but this is TONS.
