I had to turn one of my Reese Legbar roos out to free range today. He was the best looking of the 4 I kept and I had him in with the Reese pullets, but he turned mean and started attacking me. I tried humiliating him and even hurting him. Then I switched him with one of the others and put him in with the 2 other roos and a bunch of non-Reese hens. Today he came at me repeatedly, so I grabbed him and tossed him out of the coop. I found him this evening sitting on the ground outside the window, longing to get back in with his flock. I suppose a fox will get him eventually, but I can't perpetuate his genes now that I know he is people-aggressive, I have a low tolerance for that.
