When I tried to add 2 cockerels to my flock of 20 chickens I had to order them from a hatchery .All I could find locally were game because they're more popular in rural areas.
Stallions,bulls and billy goats are a lot more trouble to keep than mares, cows and does. The male is naturally a more aggressive animal than a female. People usually keep males for breeding purposes (not pets) That goes for chickens too.
