I kept snakes in Central Fla. and they bred pretty much normally. I keep pairs together, so they could breed whenever they wanted.
Also in other parts of the country, I kept pairs with a heat source and they often fed in the winter and still produced normally.
So now, you get to watch and see what happens. I would not worry about it.
Central Fla south is the easiest place to breed colubrids. All you have to do is feed them and clean cages. Which I imagine is why the big commercial breeders are there. Best wishes
