Chalk shed uses?

[BrockWinegar]

I’ve got a bunch of old chalky deer and elk sheds that I want to find a use for but not sure what. Don’t want to throw them out but they aren’t in good enough shape to be decoration or dog chews. Any ideas?

Grind them up, put them in your tea. Let your rabbits chew them. Plant them in neighbors’ yards and watch their surprised faces. Cut the points off, attach them to a club, then wear a loincloth and grunt your way through downtown. Stabilize them with resin and sell them for $$$$$.
