Our problem is not squirrels it's all the wild birds. We have an open top run and leave the feeder inside the coop, but even with the coop completely closed (except for a window with chicken wire and the small door for the chickens), and all the wild birds just go in and make themselves at home. We are amazed how much food we go through for just 7 girls. In our area, we have a LOT of doves and starlings along with the normal small birds.
We are also concerned about disease from the wild flock.
Suggestions please.
A proper treadle feeder stops wild birds. Spring loaded door, narrow and distant treadle, heavy counterweight, nothing else works for the most persistent vermin. Do a forum search, this problem was solved back in 2012, people are just too reluctant to spend the money on a decent feeder.
