Im still having doubts about Nugget and Nibbles. None of my birds are growing wattles or have high crests. I ahve 2 RIR chicks I just got and a blue australorp. One of the RIR I am very sure of, where the waddles would be, they have pink lines, so Im sure that one is a roo. And it has a high crest, but they are at least 2 weeks younger than my Australorps....yet my Australorps stand with thier chests high, Nibbles and Nugget both ahve nubby tails despite being the same age, within a day or two, of Dragon and Feathers. Now Stumpy has a nice tall crest and he seems to be turning slightly pink around the crest and eyes. No waddles though.
