We already cut them off at the store. We have a peanut feeder that is a cedar tower with holes for them to grab the peanuts out of. They've started emptying it in under 20 minutes! We used to refill it but no more. Once a day is it for them. Shelled peanuts are expensive.
Oh I know about jays, they will clean out anything you put out in no time flat. And shoo the other birds away to boot.
