You'll need to change out the bedding regularly in a coop with a wooden (or other non-dirt) floor. I use the deep bedding method (not to be confused with the deep litter method) in my large coop with a plywood floor and clean it out at least twice a year. This method may not work for a smaller coop or one with poor ventilation.Is this for your coop or your run? It's great that you never have to change it. I'm doing it!
I need help with my run. Really not sure how to keep the maintenance low there.
