Pretty snake. I have seen lessers and butters that yellow. Personally looking at the blushing on the head I think you have a possibility that it may have pastel in it. What came out of the rest of the clutch? I would call her a lesser, raise her up and breed her out to a normal and see if you get any pastels out of it. If you don't have any normals you should get some, how else do you plan on proving out your genetics or try to out breed any line breeding you have been doing? Gorgeous snake man, you made a great score, but as far as I would be concerned if it were in my colony it would be a lesser with a side note in the margin of her breeder card to keep an eye on her offspring.
