Most people suggest waiting until the females are 250-300 grams before breeding. Corn snakes can definatly breed younger though. You can put the female at risk for egg binding if she is too young. From what I've seen young females don't usually have as large clutches as adults. If you have access to a scale I would recommend weighing them just to be sure, looks can be deceiving. While my snakes are probably smaller than some who post here I feel they are too small breed. I weighed my two biggest 02s sunday and they weighed in at male 191 gr and female 180gr. I will be waiting until next season before I consider breeding them. Just my opinion.
