Okay, so here is an interesting question for you. I would love to have better fly control inside the coop- it is rather gnarly in there with flies, even with the fly catcher on the outside with yummy rotten meat in it. I do clean poop every day.. but still, they are chickens, ya know? My question- For air flow, I have 2 large windows I have hardware clothed over for predator protection, and obviously the chicken access door. I was thinking for fly prevention that I could put metal window mesh over the hardware cloth, and then at the chicken door, give them one of those walk through screen doors like you see for humans. Not magnetized though. Just with 2 sides/strips that line up on the door all the way around that they can walk through. Does anyone see an issue with chickens doing that? Being newish to them, I don't know what they will tolerate vs. not in that dept. But it seems like a decent idea, right? Thanks!!
