For some reason, if there is more than one rooster in the bunch there will be a dominant one that will develop before the rest. I had 8 Cuckoo Marans roosters and only one developed a red comb and waddles for the longest time the others did not. Then... they all developed them about the same time!
Yes, it is a slow developing rooster!
