Very interesting topic but I don't know what realy gives the best results.
This year I bred bullsnakes for the first time (I've bred 15 other different species of snakes before, so I'm not a novice in breeding).
I kept my bullsnakes in the basement for 3 months.
The winter has been very cold at some moments and the temperature has dropped to 43°F for a few weeks and has been between 43°F en 53°F most of the time.
I was affraid that 43°F would be too cold for them, but no problem at all.
The female gave me a clutch of 13 eggs that hatched all 13.
Because I saw this as a huge effort for her I did not introduce her to the male after that first clutch.
But she decided to give me a second clutch of 4 eggs and also 10 slugs.
I think that if I introduced her again to the male there would have been more fertile eggs.
The 4 eggs of the second clutch are hatching right now and I will have another 4 babies.
So 17 babies out of 17 eggs, hatchrite of 100%
So, what is the best?
Who will say? Me I don't know but I prefer to cool them.
