They'd absolutely LOVE having a nice pile of dry bedding/litter to scratch through and spread around. When I give mine cartload of dry grass clippings, pine straw, or fall leaves they cluster around so close that I have to be careful not to hit them with the pitchfork when I'm unloading it.
My DH had straw at work that was used as props from a battle reenactment. Instead of tossing it on the brush pile to burn he brought it home and I put it into my coops. It took less than 2 days for them to utterly demolish the bales and spread it all around. A straw bale with one tie cut is my very best "boredom buster" for winter.
