We're only a couple days away from coop completion and already there's things I would do differently if I could! For those of you that did not make removable nest box floors/walls, etc... how do you clean them out? They way we built them you could pour water into the boxes and it would probably sit there for a decade. Just towel out the water? Also, our perch is removable but right now is only 9 inches from the back wall. Is this okay for standard sized breeds? It can be moved forward but then there would be poop in front of one of the nest boxes. Another point of concern is that we filled the run with sand and THEN did construction. My husband's been out there with a large magnet picking up fallen screws, etc... but he used a paint sprayer while applying the sealant and there's a light coating/mist of white sealant on the sand - mostly around the edges. I should try to get this out, yes? We still have another yard of sand to add to it, but I can see chickens accidentally ingesting the stuff. I think that's it for now - thanks for your thoughts!
