I use pine shavings in the coop and run. Poop boards in the coop. I change shaving in the coop twice, once in the spring once in the fall. In the run I also use pine shavings, I scoop poop a couple times a day. Sometimes I use a little pdz in the run to prolong the life of the savings. I also dust a little garden lime when changing bedding. During summer`s humidity I change shavings once a month in the run. In the winter it can go longer usually about 6 weeks. I have tried deep litter in our run it does not work for us. Our run has an overhang and gutters so it stays dry. Too dry for deep litter, it just turns into a dusty smelly mess! I don`t thing there is a a system that works for everyone as everyone`s set up is different. But this really works well for us!
I do a deep litter method in one chicken area (much larger area they spend the day in) and in the other area (a smaller run attached to coop) I do pine shavings then moving the old shavings into the deep litter and generously replace the shavings. That happens every 6-7 days, really whenever it smells. Of course, the poop shelf gets cleaned every two days and that also gets put into the deep litter.
