Barred rock early comb development

[Ccort]

I have three barred rock chicks who will be two weeks on Monday. All three are developing their combs already but my other two breeds (6 other chicks) are not. I am curious...are Barred Rocks known for early comb development?

Not necessarily. Can you post pictures?

Done.

I even double checked. Only the barred rocks have combs.
