Years ago, we used to inject the feet with Formaldehyde, but this is a very dangerous chemical and should not be attempted. It can blind you and be absorbed into the skin. The best solution is to purchase a Deer foot mounting kit and preserve the skin/hooves, and mount them over a foot form. Try looking on
www.taxidermy.net/ WASCO supply may carry the kits. Congrats on getting a nice buck! grayghost
