I have a coop, but no run. The storage building we are converting into a coop is behind the 2 car shop, up in the back corner fences, and next to a small effiency apartment. Really tight back there, so mine free range the whole yard everyday. In the coop I use pine shavings and leaves from my trees (raked the leaves and bagged them for this). It works well, though I am out of leaves now, lol. I use the same in my goose coop, it isn't as good there because of how messy geese and ducks are, but I rake and fluff it every day and add a bit of fresh pine shavings, DE, and sweet PDZ as needed. The biggest problem with the goose coop is lack of flooring. We should have enough pallets to floor it this weekend. But with fathers day and my kids having a pool party we will most likely begin flooring on Monday or something. This should help keep the bedding dry, when ever it rains it gets soaked from flooding and sideways rain. After we floor we are going to try and install some roll up tarps to stop so much rain getting in. Will see how it all works out.
All of our leaves, last fall/winter, went into our compost pile. Maybe I'll save some next fall/winter for bedding as well. Could save money mixing pine shavings and leaves. With only 5 chickens, I don't have to fluff/clean their coop very often...but without a roost, I think I might start cleaning it more often than I have. Don't want The Ladies laying all their eggs on dirty bedding. Speaking of which...do you use anything different in your nesting boxes?
