What can you put on turkey beards to preserve them.

Borax or salt will preserve the meaty end. Change out what you use a couple of times after 2 days.

Just Pull Out The Beard And Let It Sit A While Thats What I Do

put them in a bag with some borax.

Nothing. There should be nothing to preserve on a beard. Just pluck it from the bird like you would a feather. I like to put a little epoxy on the end just to make sure it can't come apart if handled poorly.

If the turkey was taken with a shotgun and you have the spent shell, drill out the primer and put a piece of leather thru it and make a loop for hanging. Then cut the plastic shell off shotgun shell and then with a good epoxy put your turkey tail butt into the shotgun shell you drilled out and then you can hang them that way. You can also get fancy and have a plaque made, have it made big enough to hang several beards. This way you always have the shell that took the bird, and it looks pretty cool...

My thoughts exactly Feathers...
It makes a nice trophy.

I dont think I would pull off the beard. I might try some thing like a knife

Using a knife leaves a big piece of skin attached to the beard. Plucking is the only way to do it cleanly.
