I'm not entirely sure what mutation that is, but @blackoaktammy will probably know.
Just curious, what country are you in? I'm in Australia and there aren't as many mutations around here.
Those quails are so cute! I love those mutations.
Do you know whether they were from the same parents or not? Does this breeder have lots of pairs? If the breeder has a lot of pairs, the quails that are the same colour could possibly be related, but it's hard to know.
This sounds a bit like an experience I had with king quails.
I had a hen who went broody, but a few days in, her mate died. She stayed on the brood and hatched out seven chicks, but only five made it to adulthood. Once they grew up, I identified two wildtype girls, two silver boys and one...
Yeah, I picked up on that they were king quail (chinese painted).
I had a 6 week old male that I put with a 6 month old female. They bonded fine. It really depends on individual birds. I agree with what @Shadrach was saying, but it can work in some cases. It's up to you on whether you put them...
