A Chick with Four Legs

Even with four legs, this chick is still irresistibly cute. The genetic birth defect is known as polymelia, which is defined by the growth of additional limbs, more than the expected number. In this case, this chick grew an additional pair. Just like humans, chickens with polymelia can lead normal, healthy lives even with the extra limbs. Chickens have quite the memory. They can distinguish 100 or more different faces of their species and also recognize human beings. The domesticated birds can perceive colors, iridescent hues, and ultraviolet rays. Chicks are also great at making friends, and they form strong interspecies bonds and even grieve the loss of other chickens.
