How are roosters made?

Answer 1

Roosters are male chickens that develop from fertilized eggs laid by hens. The sex of the chick is determined by the combination of sex chromosomes it inherits from its parents, with males typically having one Z and one W chromosome (ZW), while females have two Z chromosomes (ZZ). After incubation, the fertilized egg hatches into a chick, which will grow into a rooster if it is male. Roosters play important roles in flock dynamics, including mating and protecting the hens.
