Hello everyone; I am primarily a Sand boa, Rosy boa, and Ball python person, but I randomly decided to ask to handle two Corn snakes that were at a reputable local pet store recently. I was immediately charmed by them both, and after considering it for a week, I decided to purchase them and just picked them up today. While I am very proficient at sexing the species I currently keep, I know that with Colubrids it can be a little different. I may have a friend of mine who keeps Corns come over next month and help me with probing them, but in the mean time I was wondering if someone here would be able to provide an educated guess on their gender, or are they a species that guessing based on tail length even applies to?
Here are pictures of them both.

(Sorry for the blurriness)





Thank you so much; I truly do appreciate it.
