Do chickens have taste buds?
Unlike mammals, chickens do not have specialized structures like lingual taste papillae (i.e., fungiform, foliate, circumvallate) to host taste buds. The taste buds are embedded in the epithelium, and grouped in clusters that surround the salivary gland openings in a rosette pattern [8,11].

Fish typically have quite small brains relative to body size compared with other vertebrates, typically one-fifteenth the brain mass of a similarly sized bird or mammal. There is also an analogous brain structure in cephalopods with well-developed brains, such as octopuses.
Do fishes fart?
Most fish do use air to inflate and deflate their bladder to maintain buoyancy which is expelled either through their mouth or gills which can be mistaken for a fart.
