I'll be following right along here as I also posted a thread last week about my MPC barred rock who's the same age.
Any chance of clearer pics from different angles to compare? Mine has less red, but the comb might be a similar size. I'm hoping, since she's still overall darker than other cockerel pics I've seen, that it's a pullet. Yours appears to have that overall darker coloring as well. Crossing my fingers for both of us. I'm probably taking more pics tomorrow when the thunderstorms are gone so I can update my thread.
