The wild birds (Bewicks wrens, cardinals, juncos) are increasingly eating from one of my chicken feeders, hanging in one of my two runs. My girls free-range, so I must leave a small door open into the run for them to return to their coop to lay. As such, wild birds go in and out of the run, too, to eat chicken feed. I'm considering building a treadle feeder, but thought the "plastic bucket w/PVC elbow openings"-type feeder might work just as well for preventing wild birds from eating chicken feed. Anyone have feedback on the 'pros' of using their bucket feeders, other than just reducing waste from billing? Do you find the wild birds learn to use the bucket feeders? My primary concerns are attracting wild birds and squirrels unnecessarily. I currently use the typical TSC hanging plastic feeders. Thanks in advance.
