Perhaps turtles that have egg binding problems are more prone to having infertile eggs. See my problem?

I have adopted out adult female turtles to novice keepers and have recommended that they not breed them. I would certainly like to warn them if there was a significant threat to their pet's survival.

I do really appreciate your help. I'll keep looking, and gladly sign in and eat crow should I find anything.

You seem like a very knowledgeable and dedicated keeper. Thanks again.
