I've had a few predator issues and in two of them Roos were involved. Neither time did they help. The first one, there is a guy who falconry hunts ine the cattle field next to my property. His falcon made a U-turn and flew a couple of hundred yards and attacked one of my hens. He left a puncture wound, but it healed fine and I still have her. My Buff Opr roo stuffed his favorite girlfriend in a corner and shielded her with his body. Adorable, but it did nothing to help the other hen who was getting attacked. Granted, him and the one he tried to protect were inseparable, but still... The 2nd time, I hear a commotion and something had snatched my little roo and taken off with him. THE ROO. Yes, that saved my hens, but I can find point of lay hens for sale by the barrel. A finding a good roo takes effort. I love having them around and probably always will, but I view them as more for my personal enjoyment than for their perceived protection abilities. These were 2 different roos. The one who got snatched was a standard X bantam mix and about the size of my easter egger hens. The scrape marks on the ground make me think a hawk got him. We had a TON or red tailed hawks this spring.
