Most of my chickens are handled minimally although all handled as chicks even when hen-reared as that helps calm them when they mature. Handling that is done with most as adults usually restricted to roosting time. Exceptions to this involve a smaller group of no more than 20 birds that taken of property for use as educational tools. Those birds are handled extensively with many trained to interact with people they do not know. Males in particularly as juveniles are inclined to peck in an effort to solicit more food offered although care is taken not to have myself or public respond in a manner that involves retreat or aggression coming from the handlers. These birds are used well into adulthood with little trouble. The trouble would be easy to realize by being aggressive or submissive to the more intensively handled birds.
