I am just a newbie at chickens (had 5 since July) so not sure how much my advice works but, here goes... I read about the deep litter method and decided to use it in the coop. I have been pleasantly surprised at how well it works. We have not changed out the litter since we got our birds. We just rake it and add more if it smells at all. I have to say, we haven't added ANY litter since we started. That was 2 months ago. Our birds free range most of the time so we only have poop from overnight, but still, I am really amazed with this method. Look it up and see if it might work for you.
