Well, the chick grew up into a chicken, but you’re still not sure how the egg got into that cave...

Locked in a coop near their owner's cottage, the chickens would often be paid a visit by curious or hungry dragon hatchlings finding their way to the coop when Mirhana wasn't looking. Although build sturdily enough to keep the chickens and hatchlings physically separated, there was this one thing that could get inside—magic. When Lochdach the Magi discovered the chickens, they proved to be the perfect targets for exploring his magical powers, sending them in a panicked fluttering around their home to escape his spells. Whether all of his 'adaptations' of the hens were intended or not is unknown, but it seems this chicken was one of his victims. A perfectly ordinary white chicken on the outside, she will start breathing fire when she becomes too agitated which, being a chicken, happens to her quite often.
