wanting to try breeding ATB

Hello I already have one and im going to the Expo this Saturday and im wanting to know how can u tell Females from a male i would hate to already have a female and get another female or the other way around. I don't have time to take it to the Vet and have her check it. What do you suggest? and what is the starting prices for ATB s at shows? I already have a garden phase i want something with color to breed with i might even get two at the show.

you can find ATB's pretty cheap if you look/haggle, your only guarantee with any snake is to probe it or pop it for sexing. Be sure you understand what breeding entails before you "jump" into it.
