We have 3 pullets that are approximately 7weeks old. Two of them look like "normal" chicks from the pics I've seen. However, one of them is much lighter (almost white) with some brown speckles on the end of its wings and around the neck. She also seems to have less fluffiness to her feathers. I am starting to wonder if she is maybe a "he." Is it normal for them to be so different in color? Does anyone think I got a rooster by chance?
