I have read on here how some females will have bumps on their legs, that are just bumps. And then there are the bumps on the roos that end up being spurs. I have one chick who is approximately 5-6 weeks old and I noticed bumps on its legs and when I felt them they were just little round bumps, but on one of my other birds the bumps were actually pointy and felt kind of sharp. Would this be an indication that the one with the pointy bumps is a roo? Thanks for any advice.
