most likely they are just splash that aren't very splashy. Could also be resessive white, "Thought to give a cleaner white than dominant white. Varieties of White Plymouth Rock, Wyandotte, Minorca, Orpington, Jersey Giant, Dorking, Langshan, Silky and others often carry recessive white genes. Many varieties carry both dominant and recessive white. Allows dark eyes. Pigmentation in chick down varies." quoted from this page, http://sellers.kippenjungle.nl/page3.html

Recessive white. If each parent contributes a copy you will get a white bird. Now, are these the ONLY chicks, or are you merely listing htat you have gotten 4 whites out of ______ chicks?
