This thing does work to kep hens from perching.  They tried a bit at first buy quickly gave up.  It keeps rain out as well *IN MY SITUATION*.  Or, I guess I should say that my feed stays dry.  I have the feeder hanging under the coop.  The coop is 4x8 and the feeder is very near the middle.  So, is the coop keeping rain out of the food, or is this cover?  Hard to say.  Don't buy this cover specifically for that reason.

Only trouble was finding a way to hang it as it doesn't secure to anything.  It just rests atop the handle of the feeder.  My husband rigged a piece of very stiff wire (thicker than baling wire) into a hanger with a hook at each end.  The cover slips over that and stays in place.  It would be areal hassle to hang the heavy bucket of food up on a hook and still keep the lid balanced unless you have some way to keep it secured.
