I don't know that I can agree with this sentiment. I have used a dremel on dog nails, and it absolutely does not cauterize them (not that cauterization is painless...). I have never used it on a rooster's spurs, however. I don't remember if it was dsfrango that suggested removing them, but I would hardly consider that to be more humane than breeding spurless roosters. The biggest problem is that it would be time consuming and possibly expensive, with a very limited market. However, I can not see any way that if it were done (as long as the roosters weren't free ranging) it would be any less humane than removing the existing spurs of roosters. Every way suggested would absolutely cause at least some pain. Plus, I'm really not convinced that the spurs do a whole lot for determined predators anyway. It certainly didn't help my largest rooster when a raccoon broke into our coop last week. The only thing that saved him was the angry peacock (whose spurs are all of about 1/2" long).
