As far as I know, the starred animals spawning is simply a matter of RNG... There's no certain "unlock" to have them appear, they are just rare and can randomly spawn where any non-star ones would... If you find a spot where boars naturally spawn, just keep killing them and eventually you will get starred one(s).
