Hi, folks! I'm a new member and will post in the New Member Forum soon, but I have a quick question now; my full grown chickens are eating all the pine shavings in their coop. Will this hurt them? Why would they do this - out of boredom? We give them lots of food and good treats every day, so they are not underfed. They seem to be OK so far, but this seems like strange behaviour... Any advice for a novice?
