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

The hatchling of a mysterious chicken egg found at the cave rather then a dragon egg, Cluckers has grown to be a wonderful (if dim) animal, and loves to walk around the cave without a care, obviously not realising how tasty some of her 'sibilings' think she could be, fried, jerked, or roasted.  Luckily, Natasin the water dragon (who hates bird meat) protects her from knowing that.  For now.
