Ralaniz, Did your husband happen to purchase the snake from that pet store that is right near Trans Mountain? If so, the few times I have been in there, the owner seems to know a little bit about corns, but his workers don't know much at all. When I told them that their corns could end up eating their cage mates, they had no idea what I was talking about...
If your husband came to Las Cruces and got the corn from Petco, I can assure you that they do not know what they are talking about... I am the only person who works there that knows anything about corn snakes... We have one other person who knows a little, but not much... If he got the snake from Awesome Reptiles, I can guarantee they do not know much about corn snakes.... The guy who owns that place focuses his attention on his Boid's.
