This is my first time preserving turkey parts, I did the tail feathers, no problem after viewing many YouTube videos, the beard no problem either but the feet are starting to smell. The videos I watched said just to cut them off and put borax on them a couple said salt so I made a 70-30 mix of mostly borax to the parts.
After a week the feet started to smell so I drilled the center of the legs with a drill bit and covered the complete feet in borax, after a week no smell. Now going on 3 weeks I can smell the feet under the borax. Is there anything I can do or will the smell just leave in time?

Thanks in advance.
