Its just odd the breeder wouldn't be selling it as a 66% het pied (atleast thats what I would assume it to be). The tracks are hardly worth mentioning, some have them some don't. Some normals have tracks. It's not even worth bothering to look at unless your trying to pick out possible hets out of a clutch and that's even failed on someone I talked to.

I would find it odd for a breeder to sell a 66% het as a normal, even if he priced it as a normal, it would be a selling point to have it labeled as a 66% het.

If your snake is a female it wouldnt hurt to try and prove her out. If its a male I dont think its worth the time and effort to prove out a 66% het, hets are really cheap and visuals are even coming down quite a bit, I would rather invest in one of them before I proved out a 66% het male.
