Blu-kote on a wound larger than a peck on the comb is drying and can inhibit new tissue growth. Coconut oil would be better wound dressing. But you need to soak his legs daily in water laced with Betadine or some sort of antiseptic (not hydrogen peroxide) until you see progress in new tissue growth.
Twisting spurs off is quite painless for most roos. I've done it on many boys over the years, and half of them fall asleep in my lap as I'm working on them. Just take a pliers, grab the spur close to the shank and twist gently back and forth until the spur sheath loosens and lifts off. Dress with coconut oil until they harden.
I've had only one issue with one rooster who happens to be one of my current roos. Usually, there is no bleeding when you lift off the spur, just some pale pink serum. That will harden in a day or two. But my rooster bleeds. This is not true of most roosters. Yours will very likely do just fine and not bleed.
I've tried wrapping his spur nubs in gauze and bandaging them, but that inhibited them from hardening. So now, I install him in a crate for a day following his spur removals, which I do every two years. I let him out during the day, but he sleeps in the crate at night so as to avoid him hitting his healing spurs on the perch when he roosts. By day four or five his spurs are hardened enough that he doesn't cause them to bleed when he is engaging in normal activities.
As I said, most roosters can go right back to normal activities following spur removal. A normal roo may hit a spur and cause a tiny amount of bleeding but it coagulates immediately. My roo happens to be a rare bleeder.
