Do you know what the origin of the Self Blues are, and do you have a copy of the Standard of Perfection? Would like to know what it says on the Self Blues for show purposes. Thanks Stan

Stan,
I have a standard, I'll post the description here when I can. I'm not totaly sure what the origin of the color is but I do know that it is a fairly common color in Europe. For some reason I have it in my head that it originated in South America....but this could be totaly wrong.

Do you want to know where the actual color originated or just the self blue OEGB?

I looked through my standard and it does not have an actual description of selfblue even though it list it. Sorry  Mark |

I was just curious about the self blues. As I have just added them and trying a breeding program that Mark knows about. And was curious where they came from. Stan

This is a cross post from another forumI'm not sure what information you want. The gene responsible for the self blue in US OEGB, etc is the Lavender gene (lav). This is an autosomal recessive gene. The Lavender mutation dilutes both eumelanin (black) and pheomelanin (red). The Self Blue variety in the US is often named "Lavender" in the UK & OZ. It is also referred to as "Pearl Grey" (Parelgrijs) in some European countries & sometimes Reynold's (or Renold) Blue after Dr Renold's studies (in the 1940's) on the genetics of the mutation. Brumbaugh, Chatterjee & Hollander (1972) have the honours of naming the mutation Lavender (lav). If you want some information on breeding self blues (lavenders), the following online article discusses how a line of Self Blue Rosecombs were developed (from self blue OEGB). Self Blue Rosecombs: www.rosecomb.com/federation/articles/selfblue.html The following book has a good article on self blue, the lavender gene & the associated problems with feather quality (eg wing patches). Old English Game Bantams as Bred & Shown in the United States by F.P.Jeffrey & W. Richardson The following is an article by Dr Renold, discussing the genetics (before the mutation was named lavender) True Breeding Blue Poultry and Bantams, by Dr E. Renold, Switzerland. American Bantam Association 1940 Yearbook. Scientific Publications: Brumbaugh, J.A., Chatterjee, G., Hollander, W.F. (1972) Adendritic melanocytes: a mutation in linkage group II of the fowl. J. Hered. 63:19-25. Somes, R.G., Jr., (1980). The mottling gene, the basis of six plumage color patterns in the domestic fowl. Poultry Sci. 59:1370-1374. There isn't much information on Lavender in Poultry Breeding & Genetics, although there is a little on how the mutation affects pigmentation, & some information on "wing patches".
