No, not all chicken breeds have wattles. The wattle is a fleshy protuberance on the neck of some birds, especially fowl, that is considered a secondary sexual characteristic. In chickens, the male usually has more prominent wattles than the female. The wattles and comb of a chicken can be an indication of the chicken's health. If the wattles and comb are pale, it can indicate that the chicken is not getting enough oxygen or is dehydrated.
