I currently have a Crimson (not proven) and a Amelanistic and a Snow.
My plans are to hopefully produce a few ranges of morphs, but I don't have anything to in depth planned for myself.
Corn snakes, for me, are my 'beginning breedings' which I will take seriously and work hard at, but before I make a huge mistake with ball pythons, I'd rather do it with corn snakes.
Plus I have a market for corn snakes, if by chance some do not sell.
