It's been about five years ago since I last purchased chicks through the mail, but I ordered two groups of the rainbow layers, after having previously ordered my own custom mix and match batch. With respect to the Rainbow Layers, I was very pleased! I recall a good variety of excellent laying hens. I can list all the kinds I've raised from McMurray, but my memory might be faulty as to the breeds that came with that particular selection. I know some Turkens came with one group (I would never have ordered those on my own, but they were fabulous chickens in every way!), some Ameracaunas of course, some Reds (can't remember if they were New Hampshire or Rhode Island), Buttercups, Silver Gray Dorkings, Orpingtons of some kind, Partridge Rocks, and of course some Pearl White Leghorns (which, although I love all chickens, seem to me to have very stunted/boring personalities). The most exciting part was trying to guess what breed the little cuties were! I had excellent luck with McMurray. Good luck to you whatever you decide!
