Did you allow them to cool or not? Mine did only because at this time, I have that set up. After I am breeding them for a while, I most likely not cool some individuals.
In the old days, early sixties, I never cooled colubrids. Then in the middle seventies, I did, then Both, or whatever.

The only thing was, cooling "set" them as far as timing goes. After that, there normally was no need to.
