Are any of you seeing a single comb? I don't. This is not a Barred Plymouth Rock, hatchery quality or not.
I'd think you'd see saddle feathers by now. What is throwing me and keeping from thinking it's a pullet is the barring. For the wide white bars, like your's has, it need two copies of the barring gene. That's only possible in males.
I'm seeing, and better photos can change that, a pea combed barred cockerel. What is it? no idea- Dominique? But those are rose comb. It's a head scratcher for sure. Again, better photos can shed more light. If you take more photos get a good one of the comb.
