how old? too hard to mesure!

My corn is about 18 inches and her thickest point is about the with of a dime. she sheds ever 3-4-5 weeks. the only problem, i dont know how old she is!!!!!!
i am guessing a bit less than a year, but i am getting mixed messages from other people.
like she dies at what u think is 14 but is really 19!!! LOL!

You take a picture of your snake, looking directly down on it, with a ruler or tape measure in the picture, then use this program to measure the snake in the photograph. It's cool.

If you didn't get info on the hatchday, then you'll just have to guess. Having said that, the size of your corn will depend on its genetics as well as the feeding schedule from hatching, so a maintenance diet fed 06 could be smaller than an early 07.

well, my corn is a okeetee. oh yeah, one more question. wich is the breed of corn snae that gets the biggest?

depends on how much you feed it if you powerfeed it it will grow fast but its not healthy for the snake

All corn snakes are the same breed, there are just different morphs. There is no difference in size between morphs that I know of.

I've read that okeetees tend towards being at the larger end of the spectrum, with miamis tending towards a slighter, smaller adult size

well thank you. i feed my snake every 5 days
