I've seen on home improvement shows that there are products that seal out/in moisture. I was wondering if anyone has used or knows of a safe product to use to make it easier to clean out coops. I'm designing mine and can't figure out the best way to help keep it easier to clean. I say that knowing that chickens are messy and I will still need to clean the coop regularly. I'm just looking for something that will help with that. thanks!
