I have 3 barred rock chicks (6 weeks) - they are the ones that I kept because I thought they were cockerels (the pullets had much darker feathering).
A bit confused about one of them, who seems to have a much smaller comb, doesn't have the rooster "stance", but has the same double barred feathers (except maybe a bit darker on the head). Legs seem smaller too.
Is it possible it might be a pullet with that colouring?
Or just a slow developing roo?
They come from a reputable breeder.
I didn't know how to post pictures, so pictures are here:
