About 15 minutes ago my male dog came in telling me to follow him to a problem. When I got outside I could here birds in cockyard cackling and both dogs ran into that direction. Then a male Coopers Hawk flew off one of my pens and chickens briefly made more ruckus. Hawk was trying to get at some older chicks that were quail size and smaller. Hens took those chicks into heavy weeds and appeared set for fight. Roosters that could have driven off hawk quicker where all confined. Dogs were also prepped to settle issue and followed hawk from below as it continued south. They must have run after it for some time as they where hot when they got back.
