So I inherited this coop when I bought the house and it is ok for now but will build a walk in one plus bigger in about a month or so. So my question is the birds free range the property during the day and mostly just use the coop for bed. It rains a lot here and the the too of the "caged" part isn't covered. Right now it is just wet dirt and some rocks. Is there something I can put on the found in the caged part like more rocks cause I can't pick the poop up and it gets soggy. Suggestions?
