Thank you for sharing that! I'll definitely look into paper bedding. I'm also definitely leaning more towards leaves and dried grass after reading some of these replies.
I live on a lake with 3 acres of wooded property. I can make more wood chips, cut more grass, and rake up more leaves than I could ever use with my chickens. But I know that some people may be on smaller plots of land, or in town, and free resources might be limited. That is one of the reasons I tried the paper shreds as coop bedding this past winter. I think most people can either make all the free paper shreds at home, or maybe work at an office and could take bags of shredded paper.
But, if you have lots of leaves and dried grass clippings, that makes excellent bedding as well and I have certainly used that in my coop successfully.
