Yokohama thread?

[paris_r]

I didnt find a listing for these-so forgive me if I start a tangent thread. I am posting some photos of my 4, 2 red shouldered roos and a pair of white ones. I am wanting toknow if they are show worthy. of the white ones the female appears to have a cushion comb but the male has a very squat pea/cushin combo. with the 2 red shouldered one has a cushion and one has the more pea like comb -they are all 5 months old in the photos, the female is very shy, so I only got 1 shot of her.

roo 2 the more social one

oh yeah-forgot to ask, what is the comb they are supposed to have in APA? the Euro standard seems to accept two kinds, but i seem to get conflicting info when looking for American standards

I don't believe they are show quality but I believe you can work with them geneticaly and in future generations you may end up with SQ..

here have a nice read on RSY..

and a SQ Yoko

another nice read on the genetics of RSY that may help you out, its from Brian R.

i was wondering if they will express more colour as they age and molt, like mille fleurs do. but my biggest concer is the conflicting info I get about combs with the breed standard in America, and their actual combs, though triple ridged, are flat like cushion combs.

another question concerning colours-since there are so many alleles at play in the red shouldered-what would be the result of a red shouldered roo and a white female?

The APA standard calls for a Walnut comb but to me the ideal comb resembles more of a Cushion (cush) comb as seen in the APA description. From what I hear, the UK standard calls for a Pea comb and that a number of years ago some Yoko genetics were brought into the US from the UK and introduced into the US stock to get better plumage color. Therefore, many of the birds in the US have the improper pea comb.

From my last round of raising red-shouldered Yokohamas I learned that with good genetics, many of the white breasted birds young birds would get the proper white spangling on the red feathers on the breast at about 4-6 months of age. And this is the real challenge, getting the right spangling on the breast with the deep Ox Blood color on the shoulders and breast feathers.

If you live and show in American you should use the American standard. There are many differences in preferences of breeds around the world, you need to stick to what is accepted in your region of the world.

Just a technicality, but if you have a Yokohama, that is the breed. If you have red-shouldered or white colored Yokohamas, that is the variety within the same breed. If the origin, type and makeup of the RS and white Yokohama is that different then they should have never been listed as a single breed.
