Effect of Autosomal Red on silver duckwing

[The Moonshiner]

ig creme as in what CCLs have? So mixing standard gold duckwing and silver duckwing should eventually give me some gold duckwing with the look of CCL without the barring of course?
I'll have to start watching for that.

Yes, you can also work on the elusive "Golden" Duckwing Leghorns that are accepted in some countries. Silver Male over Gold hens give you 100% Golden Duckwings(Females are required to be Silver to be shown)

Ah yes, they are accepted here in the US.

This is an extract from Brian Reeder on Silver Phenotypes.

"The true, fully silver phenotype (image 4) is very rare, because the female is not a recognized variety of any kind and most people, upon seeing one for the first time, think she is some type of Columbian or Ginger heterozygote. These hens are rather startling if you have never seen one, as the breast is extremely pale, almost completely silver, with almost no salmon expression at all. She also has no warm tones at all in any area of her feathering. When these hens do turn up in most breeding programs, they tend to be culled out as they are generally undescribed and non-standard.

Of course, the few people in the know make full use of these hens and they produce the cleanest white, Silver males. Silver/Silver duckwing has always been a double-mated variety, however, few breeders have ever known that and cull out the proper females. This knowledge has long been a carefully guarded “trade secret”. The ironic thing is that breeders of Silver varieties are constantly complaining about “brassy” silver males, yet they routinely cull out the females that could produce the proper males. The true Silver phenotype is homozygous for Aph^I. The female is as described above and the male is simply a black and stark white combination, with all the pheomelanic areas, both Autosomal and sex-linked, reduced to white. In many instances, these males show a small amount of white at the upper breast and may show a few spots of white in the lower breast.

In addition to the presence of S, Aph^I and mh+, most silver varieties I have test mated also carry dilute (Di) and/or cream (ig). I am not sure that either of these genes is actually necessary to get clean silver, but they certainly don’t hurt, either. Any diluter gene is only going to help remove brassiness from the silver areas. The presence of these diluters should come as no surprise. These varieties were developed long before genetic knowledge, so it only makes sense from a visual perspective that those breeders would have used any pale pheomelanic birds in their efforts to breed silver, just as any diluters and whitening genes were used in the development of solid white birds (which are known to often carry many dilution factors in addition to the major whitening gene; recessive (c) or dominant (I)).

As you can see from this discussion, the Silver varieties are much more complicated than the simple addition of the sex-linked pheomelanic allele Silver (S) to a given red variety. This discussion applies to any silver form of any variety. That means that all silver varieties, if they are clean, true white-silver combine homozygous Silver, homozygous Inhibitor of Autosomal pheomelanin and homozygosity for the absence of mahogany and may often also incorporate Dilute and/or cream, in addition to the other genes required to make the given variety. For those comfortable with using gene abbreviations, the genes of silver are S/S (S/~ in females), Aph^I/Aph^I, mh+/mh+ and often Di/- and/or ig/ig."

I have a silver Phoenix pullet that is a clean silver. She has no warm tones. I need to get a picture of her.
