Ball python copulation

[A.VinczeBPs]

There is no magical number. I had a female lock only three times give a clutch of 7 eggs last season, and when she was locked it was only in december.
Then I had a female lock many times until may, and she started building, then decided it just wasn't a good time.

Depends on the males, depends on the females. Rule is, keep pairing until you see ovulation in a female, or until she refuses a male (not this early, I mean keeps refusing until may).

Keep putting in your male, just because you don't see any locks doesn't mean they aren't happening, and plus is very early for a female to be refusing a male, she probably just doesn't know it's that time of year, keeping the male in for two or three days (then time off) should get them going.
