Rosecomb true bantam The breeds of poultry in the British Poultry Standards of the Poultry Club of Great Britain include chickens, ducks, geese and turkeys. The breed's eponymous trait is its rose comb, which is large compared to its overall body size. Due to a genetic trait tied to rose combed chickens, roosters may have low fertility.
