Hello, I have about 2 year old chickens and even the beginning of this winter is rough. I was seeing a lot about deep liter methods in chickens coops and was wondering what you guys think about it. Is it a good idea for chickens? And is it really hard to clean out when you eventually do. Just curious about opinions? P.S. Does anyone know about good Chicken water heaters? Mine all freeze and crack and i'm looking for a souloution. Thanks, !
