It is a Rhodebar hen and she is under a Rhodebar rooster right now but I want to put in with a Lavender Orpington Rooster
If the resulting chick is extended black (black with white underside), then the Orp was the father. If it is chipmunk or with light color, then pure Rhodebar. A white headspot on a black chick does not indicate a male chick, only if the chick is cream/brown and has the head spot.
