Trying it this year for the first time and I already don't like it. It's nasty. Gave the coop an entire thorough cleaning back in October to get ready for winter. We use straw and rake it around turning it daily. It just is not drying out well enough during the day and it really stinks. The summer was so hot and dry, it was fine. Everything was bone dry and no smell. But since Fall, it's gross.
Going to have to do a thorough cleaning again next week. I can't imagine how it works that some people only clean once or twice per year. I do have two ducks sharing the coop with the chickens, so perhaps that's part of the problem, but I still can't imagine this working well even without the ducks, considering how much poop 22 hens make on their own.
