Hello everyone! We have a prefab coop for 6 chickens (it's producers pride at Tractor Supply and it looks like a little cottage!). The coop instructions SAY that it can hold up to 6 chickens but I've noticed that when the girls are sleeping there's always poop covering the large door, there's poop covering the nesting box ledges, and I put pine shavings down, but they're always kicking them out of the coop. The coop floor isn't lower than the coop door opening so I can't do the deep litter method. Any ideas on how to keep my coop cleaner would be greatly appreciated! <3
