After multiples generations of crossing and selection, I finally reached during this breeding season 2020, to produce a nice complete black-headed female of the well known recessive US Red-breasted colour-mutation.
I used males from my black-breasted strain and female from the Silver “Graukopf” strain of my german friend Norbert K.J. Geißler.
The pictures under are the best female I produced this season, and I am very proud of the result.
In 2021, I will try to fix this characteristic and produce more offspring of equivalent (or better) quality.
