My issue is birds, just ordinary sparrows, finches.....getting into the coop, sitting on the edge of the feeder and gorging themselves all day. I am actually noticing I am putting more feed into the feeder throughout the week, than before I had this issue. I really don't know how to keep this from happening, as I have to have the feeder open to the hens all day. Does anyone have this issue AND a solution? I have told my 4 Marans to "keep those stinking birds out" but they apparently don't understand my request. I worry about diseases some birds can bring. Thanks in advance for any help on this issue.
