With my Miami Corn babies, less than 1 out of 5 will accept pinkies when offered. Almost all will accept lizards. About 1 out of 10 will not accept lizards but will accept pinkies. Another 1 out of 10 or so accept pinkies and lizards. In the wild, first meals of lizards might be more likely than encountering pinky mice running around. Breeders do favor those specimens that easily feed on pinky mice, whether that is really the norm for all wild Corns or not. Perhaps it could be a problem if the Corns no longer recognized lizards as prey but only accepted pinkies, due to selective breeding, like the 1 out of 10 or so I mentioned. My lines are not far from wild caught (no more than a few generations.) With selectively bred lines over decades, that percentage might be higher, and they might not recognize prey items that wild caught or closer-to-wild-caught specimens would.
Albinos of any species generally do not survive well, as a group (why they are so few in number, unless bred in captivity.)
