I've always thought 'hay' was okay as bedding in the coop..........and if the girls actually 'ate' some of it, that was fine. But, the other day, a friend who has chickens told me 'she' was told to always use STRAW in the coop....and NEVER hay..... that chickens won't eat straw, but might eat the hay, and run the risk of an impacted crop. Then someone else said to never use straw, because chickens will eat it!! So which is it!?!? Or are neither ok around chickens?
