Balls are definitely being over fed in captivity. I noticed a long to time ago if I cut back on feedings after they get a few hundred grams most never hit the 1,000 gram wall or go off feed at any point.
I also rarely have a breeder male go off feed because I don't pound them either.
I do have a few picky eaters that don't eat consistently no matter how much or little I offer. These are usually Mousers or African Rat eaters though.
