Hi, I ordered 6 CM and 6 BR pullets from MacMurray, hatched FEB.5. I can't tell them apart as they don't distinctively have pink or yellow legs. Three chicks died very young. So I have 3-6 of each breed. Meanwhile, there are 2 that seem like roos to me. They are lighter, taller, braver than the others, have no black on legs and have very distinctive white stripes. the rest have mostly black with blurry white lines. They are the central birds in photos 1 and 2. Photo 3 shows some of the others. Questions: Are the birds in photos 1 and 2 roos? Or are chicks of one of these breeds lighter? What breed do they look like? Thanks for your help!
