All of the night time poop lands on the boards and is removed daily. Because I built my run as predator-proof as is the coop they just go out there as soon as they come off the roost in the morning. So between the run and the pen, the daytime poop is not getting left in the coop. Therefore the bedding in the coop only gets somewhat soiled during the winter. It doesn't need to be changed out more than once a year.I read your coop article and admired it! I live almost to Canada so things are definitely cold and they freeze for sure. If you're only cleaning out the coop once a year, you just let them scratch it about and leave it? Isn't that similar to deep litter, or since most of their waste is landing on the poop boards, it doesn't accumulate enough to function that way? I am leaning toward your set up for sure. I am just curious having never done this before
