its hard to see in the pic but she does have a single comb, but its still real small because she is so young but she hatched out of the really dark eggs that came with my black copper marans eggs and white marans eggs so she must be part maran so something may have jumped the fence if you know what i mean lol
Can you get a couple more photos of her and a close up of her comb? The photo I see on my end is blurry.
