We only have one and he was raised with the flock, but there are some chickens he just doesn't like and he runs at them...I think he needs a mate or two to keep him busy running the field with him, because right now he freaks if I kick him out of the run for the day and runs the fence trying to find a way in, the whole time bleeping or whatever that noise is. And God forbid he flies over the fence to get back in...He is scared of heights. Sometimes he "accidentally" flies onto the roof, and about passes out cause he doesn't know how to get back down....Doesn't do that too often anymore.
