First of all, in the poultry fancy, the dreaded "roo" word is never used. The birds are cockerels and pullets when young, and even males and females is just fine.
The reality is this. Most of the birds that people have they likely got from swaps, auctions, bins at farm supply stores, or ordered from hatcheries. They're birds far below the standards for the breeds they are said to be.
True bred birds, birds bred to be true representatives of the breed standards are only bred by fanciers who wish to presever and/or exhibit the birds. That is honestly the only source for such birds.
Unless you got birds from such a breeder, the overwhelming odds are you have far less than standard bred birds. They are still chickens, maybe even good layers and pleasant birds and that's just fine, but standard bred poultry they are not. This section on BYC is designed for discussion of standard bred birds.
