Hello, Backyard Chickens Community! I could use some help troubleshooting my new coop setup. We have a coop with poop boards. I lined the poop boards with Easy Peezy (a horse stall freshener, similar to PDZ just a different brand). It's been raining every single day for over a week. Every day, when I go to scoop the poop out of the trays, flies have already arrived. They're tiny, not houseflies, and they look like gnats. It looks like they're in the Peezy too. Also, the back half of the tray (where the hens' butts hang) looks like wet sand (darker in color than the rest). After I clean out the poop, I stir the Peezy, hoping that will dry it out a bit, and things look relatively clean but not ideal, but I don't know what else to do. The next day it's the same mess. My question is, could this be due to the rain? Or are my hens are basically pooping flies--should I be worried about their health? They look irritated because of the rain (we have gravel under the coop itself but the rest of the run is just a slick mud run at this point--it's pretty miserable) but otherwise appear to be healthy. Is my coop design flawed? Should I be asking different questions? I'm stumped and could use some help. Thank you.
