I'm picking brains once again. I have been using wood chips since I got chickens last year but it seems to be more expensive and messy to clean.Do any of you use hay?I found a local farmer who sells hay for 3.00 a bale.The wood chips are costing me 4.59 a bag.My concern is that if I use hay it won't absorb as much moisture as the wood chips do(supposedly). I had a few roos with frostbite last winter and I don't want to make the moisture level in there in the winter worse.Any suggestions?
