This is a baby chick, not a dragon. So what was it doing in the dragons' cave?

Young dragons are relatively defenseless. Their scales don't grow in until right before they mature, and they have almost no strength. Once a hatchling's wings grow in, it marks the beginning of maturation. At this point they are usually left alone by their mother and begin to hunt and survive on their own.

Lil' Chickn Legs is always found waddleing around after her mother trying not to get eaten by her Clanmates. Even though her mother is just a chicken she holds a certain power over the clan. Her Clan's Leader, Polphir, outruled the eating of chickens when Lil' chickn legs and her mother joined the Clan.
