I have removed all of my J-feeders and replaced them with cheap, thrift store, coffee cups that I wired to the inside of the cages.
I have been using a sprinkler to keep my rabbits cool during the hot summer and all of the excess food was wet and wasted everyday. We fashioned some tin caps for the feeders but it didn't keep the water out. Since the cups are on the inside of the cages rather than hanging on the outside, they don't get wet. Plus, I have a tendency of over feeding my rabbits. Coffee cups are only 8 oz. It's hard to give them too much. Another benefit is that it is hard for them to scratch the food out. Some of my rabbits do that. Also, my rabbit cages are in my fenced chicken pen under large oak trees and the chickens usually find a way to knock the lids off the feeders even when we have a wire across them. They are determined chickens. There is just a lot less waste of food this way. The cups cost me 10 cents each. Half of my cages didn't have a whole cut for the feeders yet anyway. I do have to wire up the feeder whole on a few of them but no biggie.
