Honestly, it depends on who I've got at the time. Babies get fed every 5 days whether it's my balls or corns. Since it's easiest to just feed everyone at once, that's what I do. My adults will have food offered every 5 days if I have babies at the time. When it's just adults, it's every 7. Obviously, the adults will eat less per feeding when it's every 5 days but overall, it evens out.
