I don't handle my chicks and really only handle my adult show birds because they need groomed more frequently. Still, as they get older they do calm down and grow confidence, especially as the hormones kick in and they become breeding age. My adult Austrlorps are definitely the easiest for me to catch. They're also usually the first to come running for scraps and produce. So no, you don't necessarily need to handle them all the time as chicks to make them calm. You just need to give them time. Then again, I don't have any chickens riding on my shoulders, but I don't really want them to do that either.
