Latin Mass parishes never struggle to finder altar boys. And that’s say something since they use so many at High Masses. My old parish often had a dozen or more at every High Mass. A Confirmation Mass would mean having 26 or so altar boys at one time. If only Novus Ordo parishes knew what they were missing!
Always remember those days of latin classes with Fr. Picher just to be an alter boy, we had lots of boys at the classes and a lot of them entered the Seminary. Not all went on to a Vocation but enough did to keep a thriving Seminary going. My Grandfather went to a Seminary in France and got a Degree but he came back home got a Law degree at Yale [1904] and married, raised a family and practiced Law in Hartford Ct for many years. His Son [my Father] also went to a Seminary [St. Thomas in Bloomfield Ct] but went on to raise a family instead of the Priesthood. Great education and training for any young man with inclination to serve a greater good.
I think that actually helps. When I was an altar server we had 4-6 boys at Mass. The older boys did most of the work and the younger boys carried candles etc. until they learned how to do more. At my current parish we have just a couple of servers at each Mass and the young kids have to just muddle along as best they can. I think some kids now are intimidated about having to remember everything.
