My husband and I have come up with this idea, not sure it will work . Has anyone tried this? We are going to get some posts 8' long attach umbrellas to them at the top, then lay deer netting between the umbrellas. this could protect a large area from sky attack. the umbrellas are there to diswade the hawk from coming down, if he/her does decide to come anyway he'll get caught in the netting. Does this sound fisable?
