Right now I have hay for deep litter method, but it has started raining and getting wet in the pen and I think the hay is getting moldy even though I try to keep it turned and fluffed. I did attached some tarps around the pen to keep out the rain but too late. I want to replace the hay with a different litter method but I'm not sure which way to go. Cost does play a major factor. I know wood pellets are sometimes used in horse stalls, I just wondered about with chickens??? and if they would try to eat the wood pellets and maybe get sick? I buy their feed as crumbles. I can I get anyones thoughts on this, please? Thanks to all.
