Female of US Red-breasted Chinese painted quail, displaying male feathers

The under-reported pictures show a female Chinese painted quail (Coturnix chinensis) bred in my aviaries at the end of breeding season 2018.
This bird was born with male feathers: blue feathers on the breast and red-feathers near the cloacal region what normally only are present on males birds.
This female never produced any egg.
The pictures ware taken on January 29th, 2019.

February 11th, 2021: the same bird, practically one year after the first photo-shoot.
You can see that on those new pictures that the abnormal colouration is still present!

Still the same bird but pictured in the hand and with another background.
The colouration of the breast feathers is more visible this way.
