In my experience, als tend to only lay one clutch a year. They also do not seem to retain viable sperm over the winter so to get fertile eggs they would need to be bred again. Unbred females will often still lay a clutch every year, but the eggs will be infertile. Als are somewhat prone to obesity (they're pigs!) so if she's looking that plump you may want to scale back on the food.

Congrats on the new babies,
Alice
