Way better than I expected!
This is one of those things that, on paper, sounds like it shouldn't work: it's a "memoir" told from the perspective of a rooster recalling his life experiences, told as a coming-of-age story from birth. Overall, it's a pretty silly story that somehow remains grounded in its exposition and exploration of characters. The chickens all have distinct personalities, and the overall narrative kind of revolves around the need to get over yourself and come together in the face of hardship.
My only real complaint is that the story is too short. The ending sets things up neatly for the next book in the series, but I feel like the book actually goes pretty deep into an interesting direction and then stops.
