My first mystery chick was a buttercup roo who is now 9 weeks old. The little one is 5 weeks old and because of similar coloring and leg color I thought she was a buttercup too. BUT now I see a huge difference in her comb so she can't be a buttercup, she is sporting a single comb from what I can tell. What is she? I am posting pics of the mystery girl and then the roo to show color similarities and comb differences.
