They can look similar if you are using BCM roo x BR hens.... that is a sex link combo. If the other way around a BR roo x BCM hen then ALL the chicks should be barred. On a bright note they make a good meat bird.....I have some BCM crossed with Plymouth Barred Rock chicks hatching and they look exactly like BCM chicks. I am going .tp have to be careful never to hatch them together
