sounds like they are not as young as your post made it sound they are, my bad.
As for recoil, that is up to the shooter how much they want or don't want, everyone is different, what I posted is what I would have rather had at a young age since I found the recoil heavy. Lighter recoil in a shotgun allows you to recover quicker when wingshooting multiple targets, even more so if you are young and get pushed around by the recoil.
For fun I have shot 25 of 25 with a 410, I still get looked at funny every time I bring it out for skeet, even more so when I shoot a perfect round. How do your boys shoot skeet with a single shot?
