Interesting. I would love to see if it keeps that color when it grows up. And if it will pass to the next generation.
I have a male golden that has white primary feathers. Very unexpected. I bought them as week olds. Even though he is a bit smaller than his siblings. Hes a keeper. Im going to pair him up with the largest females.
I have hatched from this same bunch of mixed quail several times now and never had this happen. I actually hadn't really noticed it until yesterday when I saw that the feathers were actually white.
