Those genes are either wrong or the two of them are hets. that aren't listed or unknown. A raptor X T.albino does not produce snow albinos. Ask the breeder for more info on their parents and possible hets. Then we could narrow it down better.
Can you show pics of the parents? Its looks really snow, but no one with that genes will produce snow.
Try put a pic up and let us see if the parents or one of them are a snow.
