You need to be concerned about this. If you don't take steps to remedy it, she will eventually become crippled by it.
If she were mine, I would remove the outer sheath of the spurs by using the twist and lift off method. You do this with a simple pliers by grasping the base of the spur close to the shank. Twist back and forth very gently until you feel the spur sheath loosen then become free. Then simply lift it off.
Under the hard spur sheath is a little pointed flexible nub or quick. Spray with Vetericyn. Have some sugar or corn starch handy if it bleeds. Most spur removal doesn't. The nub will dry in a couple hours and harden in a couple days.
The reason I recommend this method rather than just filing down the spur tip is that removal will hopefully allow for a normal spur to grow back that will be easier to file down in the future.
