A diet of pellets, fruit and mealworms isn't a good one and shouldn't be continued. Please get your babies on a staple diet. BML is a good one.
Are the males neutered? Were they all together before you got them? Could the female be in heat (this can cause both the males and females to make strange sounds, lol!)
Congrats on your babies, btw! So exciting!
If you have any other questions, I'm more than happy to answer!
