We must have posted close in time. I'm practically in the Gulf so ya to me you are in the North - Cold Country.
I like your babies. But tossed my little theory right out the door, and we can stomp it down for sure.
I think. I see a Female Manchurian Gold baby there (males have darker heads). And it has a well defined pattern by the way.
So ignore the aboves where I was stabbing in the dark.
But it is interesting with my Jumbo Browns and M Gold. I had 2 Whites and I don't remember the yellow head on them. And the striping is gold on mine, yours are white. I know that mine are just saturated with M Gold throughout. I'll have to look at pictures on my puter to see my White babies later. Yours definately have recessive in them.
Your 5-7 week olds, that she gave you, are mature by the way and are ready for breeding. I still think your golds have the recessive white in them.
Is it just the camera, or do your (champaigns') have black eyes? Looking kind of reddish only when held up to the light.
Had them 3-4 years and breeds them how often? I definately think there was plenty of time to dilute there. Coturnix can have 5 generations per year. WOW. That could be 20 Generations to get to the Champaign Color. WOW. No Wait.
When did this color start showing up in her birds? Do you Know?
She shouldn;t be to disapponted in not getting BW, cause if she selects for size hers will get bigger, if they are Jumbo Browns and Texas A&M's. I am not so sure about that. How much do your older girls weigh? GEESH that's all I do is ask questions. And one leads to another.
