Well, in my honest opinion, you CAN breed year round. If you keep your snakes in a dark room, they really have no idea what time of the day it is, nor how long the days are. You are the the controller of the environment. If you keep 2 sets of snakes, lets say 2 males and 8 females per set, you can control the environment so that one set breeds in the winter, and the other set can breed in the spring. I think its completely feasible.
