One big cause is if the male, Not the female was not cooled properly. Another is the size of the female and her age, if she is under 9 ft, she is to small, or if she is younger then a 2 she is to young. Or if her weight wasn't up to where it needed to be, so the eggs could have pulled a lot away from her. Also if this is her first clutch that could be a cause of it.


Good luck and contras. If it makes you feel better my female retic laid 50 eggs, 5 were slugs 90 days later I lost all the eggs but 2 this was after they hatched.
