Yesterday, the girls were tormented by a juvenile Red Tailed Hawk for a few hours. Either myself or one of the contractors would chase it away, only to find it returned and perched upon the coop. Finally, I had remembered something that I had seen and learned about from Terry Golson during her Chicken Workshop. She had strung old CDs across her pullets’ open top run to ward off flying predators. It had worked beautifully.
