Hey knowledgeable ones, we have 2x 8-10week old black australorps one is definitely a pullet but im very unsure about the other. Here are the pics of them. Female def the pale one so no dramas there, but the one with slightly larger comb is much more vibrant and it tried to go our 16wk old barnevelder roo, but now runs away. Could this mean we've been sold a roo instead?
