Cosmo Brat

Stats
No source publishes a single income/damage/HP/attack-speed/level-curve/upgrade-cost number for any of the 136 chickens. Two competitor wikis admit this themselves: grow-a-chicken-fighter.wiki says 'exact numbers are not officially published' (then only covers 5 of its claimed '5+' breeds), and growachickenfighter.wiki calls itself 'evidence-bounded' and publishes no stat table either.
This section fills in the day we capture it in-game and screenshot it. It'll then carry Verified by us and a capture date, and not before.
Questions
Is Cosmo Brat the best chicken in the game?
Being Uncommon-class tells you how rare it is, not how strong it is — no combat or income numbers are published for any of the 136 documented chickens. Rarity and power aren't the same thing.
