|Figure 1. The radiograph shows the tarsometatarsal bone (A) with the calcar (B) protruding from it. The calcar is surrounded by an extensive horny, keratinized layer (C). The calcar and the horny layer make up the spur.||Figure 2. The photograph shows the leg (A) and the horny layer of the spur (B). Under this layer is the calcar, seen in Figure 1. The horny layer can be filed down, but like a toenail, it will continue to grow, and the procedure will have to be repeated as necessary.|

Another recommendation is to file down the tip of the spur with a dremmel or other grinding instrument. Since the spur continuously grows, like the toe nails, this procedure will have to be repeated as the spur tip grows out. If these recommendations do not improve the flock situation, a veterinarian may perform surgical amputation of the spur. Since this is an invasive procedure, the humane use of anesthesia and postoperative pain relief should be included in the surgical protocol.

Old Wives Method of Dealing with Rooster Spurs: (from someone's old wife)
Bake a medium sized potato
in the microwave until fairly soft (about 8-10 minutes). When the
potato is ready, cut it in half crosswise and impale half on each spur
all the way to the shank of the leg. Leave them there for 1-2 minutes.
The heat and humidity will soften the "horny, keratinized layer" on the
spur (see photo above). Using gloves, one at a time, grab the spurs firmly
and twist off the hard outer layer. It should come off fairly easily.
This will leave the calcar which is soft and not dangerous. The hard
layer will grow back, so this procedure will have to be repeated.
