1) Cut spurs off leaving around 1/4" on each side of spur.
2) Cut skin off and as much tissue and tendon as you can. Also remove marrow from inside of bone.
3) Boil whole spur in water mixed with some dishsoap.
4) Pull out every minute or so and work over with knife removing anything soft.
5) Repeat and repeat and repeat and repeat until all you are left with is bone and spur.
6) In small dish, fill just high enough with peroxide tocover the bone. Prop spur up in dish so the spur is out of the peroxide but the bone is in. Let soak over night.
7) Cut bone to length you want.
Below you can see the yellow is more that needs to be scraped/cut off.
I still need to peroxide.
