I have a friend in the village who does something similar with his game roosters. His wife made leather shoes and spur guards. While cock fighting here is now thankfully illegal a few still train their roosters with the old methods. It's a bit like humans wearing boxing gloves. Think of it what you will but imo it's a lot better than how roosters used to get trained.I have a rooster with huge spurs. I just wrap duct tape around them, it works really well and it’s an easy and safe alternative to trying to file or cut them.
