Cover your run with netting and only allow closely supervised free-range time.
Pretty bird. Funny story- a few years back my daughter (2 y.o. at the time) was playing in her sandbox, so she was crouched over, puttering in the sand. A Golden Eagle spotted her and apparently thought she was edible. It did this huge swoop downward and dropped out of the sky like a stone toward her. She sat up suddenly, still completely unaware that anything was going on. That eagle practically twisted itself inside out trying to put on the brakes, missed her by about 10 feet, landed awkwardly in a nearby tree and almost fell off the branch, before finally taking off. I didn't even have time to scream. That was the first, last and only time I have seen a Golden around here. Scared the life out of me. My daughter never even realized anything had happened.
