Advice, I think? My hens are laying way too many eggs! I have 6 hens. Some days I get 10 eggs. Why are they so prolific? Is it a problem?

They have about 10 square feet each in the run, get to free range a few times per week, eat layer pellet from CAL ranch, plus scratch, soldier fly grubs as occasional treats, and a few fruit and veggie scraps from the kitchen. How is this happening?! I’m out of my ears with eggs!
