My wild caught snakes (eastern and t. Butlerii) did not reproduce the year I didn't cool them.
The butlers showed no interest in mating. My eastern threw a bunch of jelly and one stillborn. (My confining clue that her cagemate was actually male, despite its unusually large size.)

I cooled them last winter, but not for anywhere as long as mentioned above. I never observed any courtship, but the girls are looking big. I'm just hoping for some lively young 'uns. I do hope to sucessfully breed Butlers, but even with wild born survivors, there seems to be multiple parts to the equation.

Good luck to everyone.
