Those snowglows are tight! Can you get those with first generation breeding or does it take a few generation to come out like those. I might try to make some next season. Just to make sure the parents are sunglow and a snow right? or are the parents something else?
You would take a sunglow and breed it to a mack snow het albino for the same gene as the sunglow. Tremper to tremper etc. Or you could take a sunglow and breed it to a creamsicle het albino.
