Give the female one full summer after she reaches a mature size. She will then lay a few eggs the next spring, most infertile. And then the second year after reaching a mature size you might get good nesting and higher fertility as long as you have a persistent male. In other words, the earliest you might expect a strong group of hatchlings would be 4-5 years. 5-6 to be safe. My oldest female had eleven eggs this year, all fertile. Only one failed to hatch in the first clutch. It ceased developement at about 5 weeks. Scott — In diamondbackterrapins@y…, “Walker, Vincent”
