I am running about 80 immature chickens around the house. About 20 are split up between 4 game hens. The balance are weaned or brooder raised. Most are exceptionally vulnerable to Coopers Hawks with exception of those on cusp of adulthood. About 45 minutes before birds went to roost a female Coopers Hawk flew right over the yard a little over a 100 feet up as she flew in a easterly direction. Her crop was clearly distended and she was flying high and level without trying to be stealthy. Roosters gave a soft warning for hawk, but most of the chicks just looked up with few actually moving. I have hawk warning myself and most chickens dove for cover. If the hawk thinks like I do, then it will be coming back to check flock out. We may be having fun if that occurs. First change will be to tie out a couple game roosters. Dogs will likely step in too once commotion starts.
