I picked up these 4 chicks when they where about 1 1/2 weeks old. One is a EE. The other 3 I have no idea what they are. They are now somewhere around 6 weeks old. They seem to be all the same breed because the legs and feet are bright yellow to orange in color. The white one I think is a roo and the rest I think are pullets. The only sign around the cages said sex links but I and the folks at the store had no idea what they where. Might someone here be willing to give a guess. It is driving me crazy not knowing. John
