Ive just hatched a batch of jap quail and have around 5 blue/silver coturnix quail. Is this rare? How will i continue to breed them this colour? I heard its a lethal gene from a wild type produced by some birds and that you need to breed them with normal wild types to produce the same colours again? Is this true? if so would i breed a blue/silver female with a male wild type or a blue/silver male with a female wild type? thanks . picture isn't mine though looked identical as a hatchling.
