A Cockatrice is a creature somewhat similar to a Dragon, but with only two legs and a rooster-like head. They are known to eat eggs, especially large eggs, like dragon eggs.One Cockatrice killed Raxtus's siblings in their nest because it was open since his mother had recently died and his father was gone so nobody was guarding the eggs.
Unlike Dragons, Cockatrices have not magical powers or breathe weapons. However, like Skreets, they can screech at sounds that, even though they are actual not loud, the sounds are painful to all living beings' ears and bones. Also, cockatrices' tails, when wiped properly, can stun through even dragon scales, diamonds, or adamant. Their tails used to be used by dragon tamers to stun dragons but very few people know this fact at the present time of the novels.
