Ugh!
As far as deer go, I have no experience in their control. They don't come into our yard, or at least they haven't yet. Larger seeds that are attractive to bullies goes into caged feeders. It won't completely stop them, but it does slow them down. Sparrows, finch and doves get just the tiniest seeds in their feeder tray, and it doesn't attract the bullies. During our feeding season the huge hordes of migratory bullies are absent, so they can't cause a problem. The birds we're feeding are generally just our resident population.
