'Copperhead' phase.......
Never did spend any time to figure out where this comes from. I will hatch out a bunch of Milk Snake Phase corns, and some will become very nice gray and red snakes, while others get this copperhead coloration. Of course, you can't see it in the babies.
The Milk Snake Phase line itself will tend to have partially unpatterned abdomens. This got somewhat enhanced when I bred Motley to them, but I have not sold any of this line as regular Milk Snake Phase corns.
I bred Hypo into the Copperhead Phase years ago, and everytime I plan on getting rid of that line, something interesting will pop out of it. Last year I bred Ultra Hypo into it and got a few completely different looking Hypos. Then the year before, one of the females threw a Ghost that looks pretty interesting.
I have found that the best way to get interesting surprises from the eggs is by putting one or both of the parents on the surplus list while the eggs are incubating. Without fail, something odd will hatch out causing me to have to keep those adults instead of being able to move them out. In some ways, it's a curse.
