I'm not really too worried about whether or not she's a she...I think she is. I have just never seen one that shows this sort of marking. She's 6 weeks old. She has blue-black feathers but lots of them all over her body are tipped with rust-colored quail or partridge colored markings. Here are some photos...I know they usually have brown markings on their breasts and she has those too but are these other markings normal for a black sex-link pullet?
