Just got this 2/3 week old buff polish frizzle. Im thinking i may have a roo because the comb is in a V shape and the other 2 polish frizzles that came from same hatch has a single comb with a knot. Is this V a strong indicator of a roo? This chick also is a tad aggressive with my other 4 week old chicks, beak to beak staring contest.
