I hadn't even noticed it until yesterday I was watching one of them walking across the yard. I thought, "Naw, that's her rear toe I'm seeing." I watched more closely and sure enough there it was. This morning when I let them out I was checking all of them and tried to catch the one but she wasn't having any of it. But there was another one that also had spurs. Ant they are almost as long as the roosters.
These two were a year old last month. No they haven't used them on me. I did how ever see a couple of hens going at it like roosters do. So I guess they could use them that way.
