Non-breeding females laying eggs common?

[MissterDog]

In general I'd say it's fairly rare but it does happen.

My female corn that I've raised from a baby, 2001, never laid infertiles. In 2016 I adopted an adult male corn from a coworker's friend, once he was out of QT and in the snake room, opposite end of the room and never in contact with my female, she laid a clutch of infertiles that year and again in 2017. I fully expect her to do it again this summer. Apparently just knowing a male is nearby (scent or pheromones I would guess) triggered her to start doing this.

Our female leachie (only gecko we have) has laid infertiles every single year since she became mature. wheeeee

Edit to add - my cave dwelling rat snakes, which were a proven breeding pair, never laid infertiles (I never paired them up), over about 2 years that I had them.

Also not sure why you'd worry about her being eggbound. It may happen from time to time but that in itself usually isn't super common. The times my corn laid, she passed them without issue.

EDIT TO ALSO ADD (I keep thinking of stuff) that same female I mentioned above has been in a room with male and female corns before, I bred two other corns in 2010; but that didn't trigger her to lay.

That's very interesting that even scent kickstarted triggered egg laying! I wonder if it's limited to same snake species or if any male snake scent would cause a reaction? Seems like every snake and reptile is different depending on the individual either way.

Aha yeah I tend to be rather paranoid and worry about scenario's I've learned about potentially happening. Different threads and videos got me stuck in the worst-case scenario thinking. So it's relieving to hear it's not common and usually it's a non-issue! Have you found when your snakes and gecko laid was there an increased aggression? Or they were pretty indifferent after the eggs were taken away?
