4 weeks old, we have only our list from MMcMurry Hatchery to go by, and all your BYC expert advice and pictures to guess what our 26 chicks are. We are pretty sure we have a roo here, but no clue as to what breed. We were waiting to see if the comb would become more cupped...if it could be a Buttercup. It is the only chick out of our order that is growing waddles under the beek. The feathers are a pure black with a rich burnt sienna brown. We think he will be a beauitful "swan" what ever he is, from this ugly ducking he is now. Any ideas?
