Then also if it's a cockbird it could be split for blue or brown and if so could throw 50% Ash Red offspring I think...
quoted from FranK Mosca's website...
As breeders, we happen to find the color effects pleasing so we keep the mutation around and try to raise more birds carrying it. Since this particular mutation is a sex-linked dominant, that's very easy to do. All we need do to get more Ash-red birds is to pair an Ash-red with any blue/black or brown bird. If one pairs an Ash-red hen with such a cock,
allAsh-red youngsters in the nest will be cocks and
all non-Ash-red birds will be hens. If one pairs an Ash-red cock with a blue/black or brown hen, one gets Ash-red youngsters of both sexes, as well as other colored young of both sexes if the Ash-red cock happens to be carrying any other color factor (i.e., if it's heterozygous, rather than homozygous, for Ash-red.)
Please note, and this is important, with Ash-red, the bird's pattern is still visible. We can look at an Ash-red bird and see if it's a barless, bar or checker. Unfortunately, we again meet one of those worms caused by the difference between genetic jargon and fancier jargon. What many racing homer breeders call "barless mealy" is almost certainly not a barless pigeon. Rather, it's usually an Ash-red bird, barred or checkered, which happens to also carry a second mutation called
Spread.
