I have recently put some grass cuttings in one of my hen houses to try as a bedding, and it turned out better than I expected. When I cut one of our smaller lawns I put in all the cuttings in a 4x4 house which gave about a three inch layer on the floor. The grass gives off A LOT of heat as it breaks down and for that reason I think it is brilliant for winter. Other bonuses I have found are that it composts well, is free, the 10 hens in that house love it. I think everyone should try it, I know that I will continue to use it.
