So far so good! Individual rates of development vary of course, but I think the majority of cockerel combs, both single and pea, will start developing by 6 weeks.5 week update: There's still no color in the comb, despite what the pics show. I can't see where it's grown at all. The patterning seems to have mellowed out a bit on the wings, I need to get a pic of that. I have two others with EE patterns, but they have single combs. At what age do those start changing? They both look the same, small and no color.
