I have 2 Roos that get along perfectly! and 1 3 month old roo that is working his way into the flock - he is low man on the totem pole. The older roo is a Bielefelder who is 1 year old next week. His little brother is a Crested Cream Legbar who doesn't fight with anyone, but does try to keep me in my place by pecking at the back of my knees. I've never seen any fighting between any of the roos. They exist peacefully, which was a surprise for me. The youngest one is ignored except by the occassonal hen who chases him. Last week I noticed a quarter sized area on the CCLs chest that was missing feathers. I will try to take a photo ASAP but I am wondering if anyone else has experienced this? At the moment I have 19 laying hens, and the 2 mature roos. None of the others are showing any feather loss. Help!
