do both male and female have a tiny bump on the back of their legs down by their feet? Or is it just roos? Mine are a little over 2 weeks and I see some on some and I don't really see it on the ones that I got out of the pullet bin.
Yes, both males and females have spur bumps. It's not a reliable indicator of gender. Cockerels take quite a bit of time before theirs turn into spurs. My 8 month old cockerel still only has 1/2 inch spurs on the backs of his legs.
