I bought chicks from Tractor Supply the weekend of Easter. They told me they were Plymouth Rocks, but now I am not sure. 2 of them are Partridge Rocks, and I think the others are Silver Rocks, but I cant find pictures that look like mine. They have the same markings as the Partridge Rocks, except that they are black and white. they were light colored with large brown stripe down the back with white stripes beside it, and a stripe by the eye. Can anyone help me identify these chicks ?
