you can get pewters from breeding a steriling to something else? Odds must be low on that right? I may be wrong I just got back from a 7 hour drive not too long ago lol I figure you would get pastels 100% het pied, Cinnies 100% het pied and maybe some norm het pieds or what you mean when you say pewter pieds it the breeding of the offspring from this clutch. Please help my brain hurts.
Sterling is a super pastel cinny, so all babies will have the pastel gene and each will have a 50% chance of being a pewter. No chance for a normal - that is what is so cool with homogeneous genes.
