You can also try wood pellets as coop litter, the kind you burn in a pellet stove. You have to make sure to get UNTREATED ones, though. The treated ones have a chemical that isn't good for anyone. I used shavings for a long time, but then switched over to pellets on the advice of my friend at a feed store. I will never go back, pellets are awesome. As they come in contact with liquid/poo/etc, they expand, and eventually break down into sawdust. We compost everything, and they break down way faster than the shavings do in the compost heap. In the long run, you save money, too, because they last a lot longer than the shavings before you have to swap them out. We have ducks, turkeys, chickens, quails, and guineas (as far as birds go), and no one has tried to eat them.
