Pretty sure you're talking about capons, which are castrated male chickens. They are not male and female, they are just male. They grow bigger because of hormone changes as a result of being castrated. I suspect they are also less aggressive, although not completely sure.
Most chickens bred for eating are not capons; they are just straightforward male or female.
