We just got our first girls, a set of ten 7 week old chicks who came from a McMurray brown egg layer mix. Some of them we have good guesses on, a few RIR and two black Giants, but a few other I'm less certain on. There are two all white ones that I am assuming are white Orpintons, but the third white has greenish legs and has some gray to her head feathers and small traces of gray elsewhere. I don't know my breeds enough to know who has greeny legs. Also, do all the various buff colored birds start out with some white or are my two buff/brown ones with small white patches somegoing to be more mottled in coloration. In the end I am not sure it matters too much. They are unbearably cute and fun to be around!
