We got an assortment of chicks and I originally thought that the redish ones were Rhode Island Reds. But now that they are 1 week old and starting to grow wing feathers I am seeing some brown markings on the wings. Is this how Rhode Islands start? I figured when the feathers started coming in they would be the solid red coloring, so I am wondering if I am wrong about this breed. Does anyone know what breed these chicks are (just the red ones in the photos)?
