I am asking for information on how to obtain deer, elk and bison skulls during a hunt?

Just hunt and skin them. You'll get the skulls by chance.

I think it is every third or fourth kill, you get a skull.

it's completely random if it drops or not, just keep hunting them.
Funnily they can also drop from the female animals, so you don't have to go specifically after the males with their big antlers.
