Questions from a newbie... How high should we hang the feeder off the floor of the coop...and will hanging it solve our recent problem of the chickys wasting it all over the floor? They are about 6 months old and they have just started doing this. It's everywhere! I want to get our galvanized waterer up off the floor, too. Same height as the feeder? One more question...I'm thinking about fashioning a cover for the feeder? Right now they roost on it and poop inside, but in photos I see of other folks coops I don't see covers. Hmm. Thanks!
