My 18" p. pardalis female just spent a week mating with a loaner p. pardalis male, her first contact with a male in her 16-18 year life. Today, 12 days after her first mating with the male, she laid a clutch of eggs.

What do you think the odds are that these could be fertile? I have no idea how long the normal time lapse is from mating to egg-laying, and of course since females can retain sperm that makes it hard to know. She's bee laying big infertile clutches, without any male contact, like clockwork for years.

I'm incubating them but advice/opinions are welcome
