Why doesn't chicken get a second name?

Cows get beef and pigs get pork, but chicken is just chicken.

What's the deal?

@SecularJeffrey Poultry? But I think that may be a very specific type of chicken.

Poultry is chickens, ducks, geese, and turkey - the domesticated Galliformes and Anatidae. Arguably also peafowl and pheasants since in some places they're domesticated.
