Some need to be done yearly..some never..and some every couple of years.Oh...and Del...on the spur removal -
-After you remove the outer casing, how long does it take for it to harden up / heal?
-I assume the casing grows back and needs to be removed again. How often is this usually done?
It does not take long to harden at all. Some even saw the whole thing off right down to the leg and use styptic pencil or liquid band-aid for the bleeding. I have never used a saw or a nipper. I am too chicken.
