Thanks for the advice, I'll watch the female closely and hope for the best.

Out of my 3 males only the lemon one has been active in copulating with this female, the others have shown little intrest towards my females. Well, at least I have hopes for some lemon babies. If not this year, maybe next.

I've gazed at the pix at www.ballpython.ca gallery but I don't feel confident in being able to recognize the building or glowing when or if I see it, maybe I'll even miss the ovulation.

Does the female's weight change during the period before laying?
