Oh,I know about pen fights...two of my Asil roosters were fighting through the fence and both roosters ended up having bloody faces and one had torn up foot pads from trying to kick the other through the fence...I won't be putting them next to each other anymore,lol. I understand why they fight,but I don't u derstand why the have to fight until one dies...it irritates me that they do that,but I guess that's just the breed they are...
