I have 3 chicks, all different breeds, born 1 day apart. They are Dominique, Delaware and correct spelling if I'm wrong, Americauna. The Delaware and Americauna showed their combs coming in orange at 4 and a half weeks. At 6 weeks today, the dominique is still yellow combed. I bought them sexed, but I'm not sure. I wanted all hens, but it appears to be 2 roos. The Delaware is the smallest and the Americauna is the largest. HELP PLEASE, and so sorry, no pics.
