Interesting. You have the roosts above the nests with the area to scoop out the poop? Never seen that idea. Great idea.
Yes, it is very easy to clean. It just takes me about 10 minutes to clean the whole coop with 4 roosting boxes. 19 chickens can really make a mess every night but scooping the poop in the boxes is very fast and easy. I used to have hay in them originally and I didn't like it at all, too much waste and very messy.
