  1. While all slugs are in fact infertile, not all infertile eggs are slugs. If attempting to educate the novice, for the love of reptiles, give accurate information! It’s not as if it’s new information or even debated information. It’s terminology that’s been used for over a hundred years. And it’s terminology used for ALL egg laying animals, not just reptiles. Miss used terms leds to miss information &/or confusion. There’s enough of that out there already.
    Slugs are formed when the reproductive female is lacking a particular nutrient in the formation of that one particular egg. For example if her body didn’t provide enough calcium or enough amino acids for the yolk protein, then the egg will not develop properly and forms a slug. An unhealthy female could produce several slugs. Just as a healthy female can lay several clutches with healthy eggs that are infertile.
