I have all hens and 3 roosters. My first 2 Roos were the more tame kind, and they don't have long spurs. My 3rd Roo, on the other hand, had long spurs and is very aggressive towards me and my family. It really upsets my because he was such a nice rooster until we got some smaller hens his size. (He's a self blue oegb btw) I want to trim his spurs, but do the spurs have veins that I could nick? I started with some dog clippers at the end of his spurs, but didn't go any farther because I was afraid of hitting any veins. I want to take the most of the spur off but I don't want to twist it or anything like that. He seemed calm when I was clipping them though. So, do they have veins running in their spurs? Thanks in advance!!!
