I know it is illegal to kill a raptor but I never knew a Great Horned Owl was a migratory bird. I also learned from this article that they attach knives to the cocks when fighting them. I always thought the roosters used their spurs.
No, they cut the roosters spur and depending on the match, it'll be a metal spur, short knife or long knife.The spur has different rules than the knives. The spur matches will consist of 2 spurs per cock, where as the knives will only consist of one blade generally tied on the left leg.
