They are eating the wood shavings in the coop, I know that can hurt them but how bad? How do I stop them??? My mother was at the store so I asked her to please by some shavings. But she didn't have time to go to orchlens to get the stuff we normally buy so she went to nixa hard warestore and bought a diferant kind. THE shavings are pretty small and now my chickens are eating it!!! hElP!
