Leigh will probably confirm, but I'm guessing that she got one from the clutch that she's not sure is a het red or a normal and is hoping to prove it one way or the other by breeding it.
But you are correct that a het red is a visual morph, the super being a red axanthic (just like YB and Ivory).
Ok.. lol.. understood.. I knew het red was very suttel morph, and I think that is the reason it was concidered resesive at first right?
