Crows and bluejays here are the ones that harrass hawks and drive them away. Other than that, I just depend on my roosters to keep the girls safe by being on alert and warning them to dive for cover. So far, no losses, though I've had hawks swoop through here often.
Tried putting up gourds. The bees built nests in them.
