Best way I've found to do it is have a taxidermist do it....grins, nasty job....
That is what I think I'm gonna do. Keep the head frozen till summer and stake it down with a cage around it.Dig a hole stick the head in it with rack above ground and let the maggots do the work. Just make sure no squirrels get to it. I have a buddy that does it all the time and it clean and easy. Not sure if you use some sort of bleach mixture afterwords to whiten up the skull.
