Mice or crickets.
There is no special age, I have known people as young as 7 years old with corn snakes.
My oldest is 7 years and the youngest 3 months.
1 year
I've heard the oldest on record was 40 when it died but who knows, there are probably older ones out there.
Not necessarily. The term chicken snake can refer to several species of snake. The corn snake is one of them.
medium corn snake:sub adult , adult corn snake:adult
yes a hatchling corn snake can go in a vivarium with an adult corn snake but only if the adult corn is very tame and feed well and there needs to be lots of hiding places for the hatchling corn snake to hide about 5 hides
The length of a Corn snake can be up to 72 inches.
A corn or rat snake would be good. I'd go with corn snake. They're esey to take care of, as far as snakes go, and you can likely find one in your local pet store.
Rat snakes are generally black whereas corn snakes are orangey yellowy and look like ground up corn.
Ask around on Kingsnake.com or a corn snake forum.
