No, not only sun. Too much corn will turn a white bird yellow. It can be genetics in some cases, too.
Hey, there are three BBS Orps in there, too, right Kathy? I see Smoky's characteristic long egg, always clunks in the turner, LOL.
Most males have more shoulder smut than pullets do, and it travels down the back, between the shoulder blades, but in a small percentage, they can fool you and you would have a not so well marked male or an excessively marked female.
