i have 4 BCM chicks that are all 6 weeks old. One is much larger and is the only one with a hint of color in its comb, the rest are still very pale pink. Here is my suspected roo.. I have never owned BCMs before so I am unsure of what to look for in male to female coloring changes as they mature..
Here is one with a pale comb for comparison
