Self Blue (lav gene) shows up unexpectedly?

[onthespot]

I'm no expert but I vote splash.

Hello all, (Hi L)
I am the 'infamous' breeder of the Lil "Blue" (LAV) pullet and her siblings and offspring. I can assure you that with out any doubt (as Maury Povich would say.... 99.9999% acuracy) that the pullet came from FULL CLB/BCLB DUTCH parents.
The location of the cage in reference to "ANY" of my other birds (clear across the pen and 4ft higher than the Leghorns) with only LB DUTCH in the opposing pen makes it impossible for any other mating.
Never where any my females in any other cage than with Dutch.

I want to comment that I believe the rule is if the shafting on the feather is of a darker color than the feather, the bird is considered blue or splash in this case, if it is the same even color, then it is a lavender. The one pullet looks to be a blue and the lightest one I see black flecks so I would guess it is a splash though not much of the dark blue splashed on it.

jwolfe,

Do any of your cockerels have a missing wingtriangle, I mean a crowwing.
There could be traces of a wingtriangle, the crowwing does not have to be perfect.
That is the most apparent difference between cockerels with the e+ allele and those with at least one birchen E^R or extended black E allele.
The latter alleles would be necessary for a unicolor pullet.

e^b plus a lot of melanizers would also be possible.
These melanizers would show up as heavy hackle striping and in the pullets also as heavy stippling.

Have any of your hens been fondled by breeders that have unicolor dutch or a similar breed?

Hi Henk,

I can answer for Jeff I think. The BCLB cockerel (you would call him BlauwGeelpatrijs) has a lovely wing triangle, he's actually a very nice bird.

Cara,

Actually, (as you would likely know, since I sold you at least one BC bird), my Blue Creams all have small flecks of black in their feathers from time to time. I asked Jean Robocker and LeJean Marshall about it, and was told it is normal for BCs here in the US.

I am working on some pictures I took yesterday evening of a typical Blue Cream Light Brown hen, comparing her to a typical Blue Cream Light Brown Splash hen, for everyone to see.

After all this thinking and talking and reading, I have come to the conclusion that the pullet in question is likely an Andalusian Blue, a bird who has somehow either lost or had her Cream (igig) gene suppressed. Not sure how it happened, and the real test will be to breed her back to one of the others who appear to be without igig too and see what they produce. It's a project Jeff and I are committed to working on, and we thank you for your comments and info. See my next message for the pics.

Hello Laura,
Her cream gene probably hasn't been suppressed, it is probably just not showing. It is not the cream gene which gives a different colour neck hackle or breast to the rest of the body, it is the gene at the e-locus, e+ (wild type, duckwing, etc). The cream gene just affects the gold colour when the gold colour is showing. In the pretty pullet's case the gold colour is not showing so one cannot see the cream affecting it.

Best wishes

So what would make the gold color not show?

Jeff just sent me pics of the underside of her wing and tail, so you can all look at the color of the shafts of her feathers (ignore the little spots of dirt, she's in a breeding pen):

Ok, here are some more pictures. I took these last evening, of a typical Blue Cream Light Brown hen and my one Blue Cream Light Brown Splash hen:

A different gene at the e-locus or melanising genes or both.
