Roos do molt their spurs every so often, just as they do their feathers. If you look around you might find them lying in the coop. :) I have one from my beloved old roo, Jack, that he molted the year before he passed away.

Just check the spur area and make sure there isn't any obvious injury or signs of breakage or disease...also check your other roo and hens to make sure that the missing spurs aren't lodged in your other birds' backs--if they are they can cause a deadly infection.
