I am hatching out the eggs from my first little flock of coturnix. For a while, I had our "regular" coturnix and A&M's together... some of you may remember I have since separated them b/c of scalping of the A&Ms.
So, if I have little yellow babies hatching, is that indicative of A&M coloration? Is it a A&M+A&M or could it be wild color+A&M?
Say a Brown carries A & M (or english white) and you mate it to an A& M or english white.
A small number of that birds chicks have the opportunity to become A & M (or english white)!
Brown is dominant over A & M (or english white) so it's color takes over mostly, but if it carries the the white gene and it mixes with the white gene of the other bird you get a resulting white chick and yes yellow is indicitive of white OR tux if it's got a lot o fblack on its back which yes theres even a LOWER percentage that could come out tux as the white bird automatically carries the tibetan (range) gene from what i read on genetic thingies
I've never had brown to A & M produce tux but others have it does not produce a brown tux though it produces a range (tibetan) tux
Or you had a dominant A & M roo that was breeding the A & M hens
Either way it takes 2 whites hidden or visual to produce white
Actually, if you have browns that carry white, and you breed them to white, there should be about 50% white chicks from the breeding. 2 birds that are brown but both carry a gene for white would get you approximately 75% browns (with 50% of these being carriers for white), and 25% white.
