I knew that roosters grow spurs, but holy cow! I just saw the scariest looking things in my live. I'd like to know a few more things on spurs. 1. When do they start growing. My cockerals,I was told, are about 16-18 weeks and they are just little knobs. Are my guys younger than expected? 2. Do females get spurs? Or do they stay little knobs? 3. Is it more promident in some breeds than others? I am wondering, not for my sake, but for my children. Any information or links and even pictures on this topic is truly appreciated.
