my chickens (11 weeks old) are in the midst of thier first molt and there are feathers all over the place. this weekend i noticed some of them playing with, and then EATING the feathers. what's up with that? i can't imagine it's good for them (pretty hard to digest, i would think). should i be cleaning up the feathers from the coop & run? is this "feather eating" normal? i've only seen a few of them do it, and have never read anything about this behavior. i just think it's kinda wierd. any thoughts? thanx.
