question on colors in silkies?

And I definitely agree with your last sentence. I am a strong believer in Murphy.

Pg is is carried in partridge. and your not wanting to double up on that because of the barring it can create.

I'm not sure anyone is talking about involving partridge birds as such.

I see what you are saying about Pg. I agree that one would cull against if one saw it. Both buffs & black based birds can carry Pg.
You are referring to autosomal barring from Pg & Db? If Pg came from a black & the Db from they would be homozygous less often as they hav linkage? But that is an interesting point. I'm pretty sure my buff orps carry Pg,Db & Co (among other genes) I only get the concentric pencilling markings, only in pullets & only in such areas as would seem to indiacte that they are het Co/co+.
Like this pullet, (though this pullet also has sex linked barring).

I don't remember ever getting autosomal barring in adults; I couldn't, however, be certain as I might have culled against it long before they matured.​

Yes, but if she was breeding F1s back to lavender silkie the F1s would only be carrying one frizzle gene. So only 1 in 2 would inherit that gene.​

Are buff silkies wheaten (eWh)? I had thought they might be eb.
Most are e^b, not e^Wh. Any with greyish undercolour are e^b; any with females that have more than a tiny amount of black are e^b
Pg on its own wouldn't cause much of a problem. Pg is not only carried by black based birds, it is sometimes found in buffs too. Particularly on a eWh bird, it wouldn't really show if Co & Db are homozygous, & melanisers aren't present.


From the F2 stage onwards one would need to go by selection. With so many genes being in buff there would be quite a few different phenotypes occurring. Not sure how well they show in silkies. With selection & culling it ought to only take a few years; I've done similar projects in Orpingtons.

I suppose much depends upon how far towards the isobel silkie one wants to go. The so called "porcelains" appear to be more of an intermediate stage. This ought to be a good bit easier to get to than the true isobel silkie.

The more black pigment in the bird, the more lavender, the more red (buff) pigment, the more isobel.

heres a lavender

Here is a P Isabelle

Here is a splash

it is very hard to tell them from a light splash as chicks but the feather shaft colors are a bit different, I cant remember though which it is I think the dark side of a lavender feather is on the outside of the shaft and lighter on the inside.

The more black pigment in the bird, the more lavender, the more red (buff) pigment, the more isobel.

Well quite. Thus the more black pigment the more towards what they are calling porcelain.


A happy chick. Your Isobel is not what I'd call isobel though it could be going on for what people are calling porcelain in silkies.
Why has your splash bird got a salmon breast?

The underside of lavender feathers often have a dark shaft. The outer side will be lavender. Blue has darker shafts either side​

Wow..... I am learning more than i expected. Very good info!

The splash is supposed to be split to lav, I believe he was in a project pen with lavs, splash, and PI I think the other colors have bleed through I will know for sure when these next few eggs hatch out whether he is split or not but came from a reputable sorce.

The PI came from George Mihalik the pullet has better colloring but I got them from him myself and am aware that he is playing with colors a lot.

I have true splashes with good even coloring I just posted him because thats what I had on page one on photobucket lol

heres the pullet from G.M.

I think AHAPPYCHICKS silkie dosed w/ lavender would be the resulting color of my silkie on my website listed earlier.

LOL now I'm really getting muddled up by hobby names.

To me "isobel" was homozygous lavender on buff.
I've just used to the idea that silkie people are going to call intermediate lavender/isobel by the hobby name of "porcelain" & now we're getting "porcelain isobel".

Your pullet's colour is rather effective Ahappychick. The colour looks to me like it could be a silkie version of quail? Melanised eb with columbian (& homozygous lavender). The male looks like it might lack columbian or dark brown columbian. What colour is his breast?

Friedeggs, did you have trouble with pattern gene?
