That sounds like a great feeder. I’ll go look and see what Tractor Supply and Farm Supply have.
You must be growing some genius squirrels down there, being able to collaborate with the birds.
Everything here was fine until one squirrel figured out how to hang on the feeder upside down. Before that a lot of the birds didn’t like the little seeds so they would knock them out to get the sunflowers. The doves and the squirrels would stay on the ground eating. I was fine with that! And then one got greedy
Many years ago when we first moved into this house there was a neighbor next door who put out bird seed. We ended up getting 100’s of black birds sitting on all the roofs. They even started building nests under my eves. I WILL NOT put out a bird feeder.
