You will know when you feel them. As the female moves through your hand they tend to slow down as you get to the follicles and then they are easier to feel as your fingers slide over them. I don't count them as developing till they are nickel sized. And I know that ovulation happens after they are walnut sized.


They are harder to find in bigger snakes. I can never get a good count in them till the follicles are much bigger than nickel sized......
