I bought a feed supplement suggested here at BYC & was told it helped stop feather picking. Its called Forco. I questioned this after going to there website because its for horses. Anyway I bought the stuff & now I'm not sure how much to feed them & how often. I asked but got no response. Now, I'm kinda Leary to feed it to them at all. Has anybody ever fed their chickens this stuff? Should I use it or not. Thanks 7L
