I'm not sure it'd be working out how you see. In the show it timeskips a bit something multiple weeks, or months. You'd be a baby chick unable to comprehend things for at least the first part of the roleplay. Up until maybe the week after we stop the first wave which in game is meant to be two weeks. You'd also be unable to make a backstory (a requirement for the CS) for a character that literally just hatched. And having a fully grown Filo King, or a young one just wander into the party seems a bit out of place. If you want me to recommend something I'd play a bard, or something other that lends itself to silly actions, and then have your king idea possibly come in later.
