Impossible colors and patterns

[flyingmonkeypoop]

Just wanted to point out that the black/orange birds with the yellow in the comb nica posted a couple back are Ceylon junglefowl not green hybrids

I think you may (hypothetical) be able to produce a blue spangled bird ( blue base color with black spangles). The bird would carry extended black (E), melanotic (Ml), dark brown (Db) and pattern (Pg) and heterozygous for blue Bl/bl. It would not make any difference if the bird was silver or gold.

My rational is that birds that are blue can express black i.e the black pyle zone in andalusian males and lacing or edging in male or female andalusian. It is the black produced by the pattern gene and melanotic that will stay black and not be diluted to blue. The black which is due to the extended black gene will be diluted to blue.

The pattern gene and dark brown gene will form the blue spangle.


That would be an interesting project.

Db would also restrict on E base i.m.o.
Gold or silver groundcolor would show up.

I dare to disagree with you guys here...

I'm enjoying the show. I thought perhaps it would be possible to select for the 'shape' of the lacing around the Andalusian blue feather, as someone else suggested, but that would take for-bloody-ever....and may not even be possible.

How does your garden grow?
With silver laced and pearly brahmas
And pretty silkies all in a row.

I'm not allowed to bend over, and my knees don't do much squatting or kneeling before they break*, so the kind of big mixed perennial beds I used to keep are outside my ability these days. I'm not into herbicide and bark, either, and I've wanted chickens for ages and am using the shaggy garden as an excuse to indulge myself now. Something new to think about, too, which is always good for the aging soul. And I can point to the possiblility of eggs, meat, and gourmet consomme when the farmer part of my brain protests.

Poultry keeping is full of nice intellectual challenges; trying to figure out how to make new varieties is one of the best.






*59 years of farming while clumsy, including multiple dislocations of the shoulder, hips, knees, ankles, and costal cartlage= less well able to move than I might be.

I keep wondering about the spangled American Game that's in the credit footage of the TV show "Justified"- a Spangled Hatch, I think, and a mind-blowingly beautiful bird.
