My neighbor keeps doves and pigeons and chickens and some other types of little birds in his yard. We have tons of little wild birds in our other neighbor's trees against our backfence. Every evening, there's a hawk that's sitting on the telephone wire above our yards. A soon as it swoops in, you can hear a rush as all the birds take off and then it's silent. I'm concerned about letting the younger chicks run around in the yard. I guess there's nothing to do about it besides keeping the chickens in the run. The hawk is not that large. Would it try for a larger chicken? My other chickens are around 3 months old and quite large imo.
