Impossible colors and patterns

Yeah, that was what I was afraid of. I may still work on a Ameraucana/SSH project, because the idea of a Hamburg laying blue eggs sounds cool. There's someone local to me who's breeding Lavender Hamburgs, so I know that it's possible to reduce the gene on the spangling with a silver ground-color, which may be the next step to consider.

If you want a Hamburg that lays blue eggs, I suggest you search for a single or rose comb chicken with the blue egg gene to cross with your Hamburgs. That way you could avoid hatching the large amount of chicks needed to get a cross over.

Silver does not dilute black, Lavender will dilute black on a gold based bird also.

Any suggestions for a breed that fits that description? I'm well on my way to memorizing the Rosecomb breeds on Feathersite but nothing rings a bell- especially since I'm looking for a light rather than heavy fowl.

I was assuming that the "silver" in SSH indicated a silver gene for the ground color rather than, say, recessive white. I suspect the "silver" in the name is pre-scientific?

I've yet to read a coherent description of the developmental mechanism by which SSHs end up with white feathers with black tips, (or GSHs gold feathers with black tips, for that matter) and was hoping that the pathways which isolated black tips from white/gold/citron shafts might be such that one could have dark spangling on blue shafts.

Cream Legbars and Isbars have single combs and have the O gene. If you do a search on google you may be able to find someone with some they have created as well.

You are correct, silver is a completely different gene than ether dominant or recessive white. It takes the place of gold and seems to clear up "mossyness" on spangled birds as well.

Wouldn't barring be a complication?

The only way I can think it might work is if the mutation affects the structure of the feathers. In chickens, there really isn't a "blue" color, but a dilution of black. In other birds that are "blue", the color comes not from a blue pigment but from the structure of the feathers, which causes light refraction, and thus melanin appears blue. If a mutation occurred that altered chickens' feathers to have this structure, blue and black could appear on the same feather. I know the pattern already exists in budgies (blue opaline budgies have black-edged-blue feathers along their back).

It is one more gene that would need to be bred out, and Legbars are also duckwing based. Isbars would be more ideal as they are based on birchen.

If you cross an Isbar to a Spangled Hamburg, and then take the offspring from this cross and breed them back to Spangled Hamburgs, about one in thirty two will be a homozygous spangled, blue egg laying female.

only if you can change ground color(Gold and Silver) to a bluish color.....

and Here I thought producing a Pink Bird was crazy..... Eumelanin can be change to many colors(Blue,white,Chocolate,Beige,kakhi) but Pheomelanin its Trickier, it can go from the Darkes Red(R.I.R) to plain white(Columbian Rock) and everything in between but to Blue..? I dare to say IMPOSIBLE.... but I´ve Been wrong before...I will love to be prooven wrong

Blue's already a color in chickens- my icon shows my Blue Laced Red Wyandottes, and I was thinking of crossing Blue Ameraucana with Silver Spangled Hamburgs- the point being a blue bird with black spangles who would lay a turquoise or aqua egg (Hamburg eggs are cream). Blue chickens aren't Bluebird blue, nor Indigo Bunting blue, but rather sort of gunmetal or almost French Blue.

This is the blue chicken thread that was started yesterday.

If you cross Blue with Silver Spangled you can get a Blue Silver Spangled.
(Replace the Black on a "regular" Silver Spangled with Blue)

That number is why I won't be doing the project until I've bred up my Hamburg numbers.

Yeah, I was sort of referring to that above (w/ reference to both the blue-spangled gold on Feathersite and the existence of Lavender spangled local to both BYC and my physical location). It might be the way to go, although the best moderately-sized blues I have access to are Ameraucanas and the difficulty of breeding out the pea comb is as daunting as breeding out barring. Blue spangling sounds cool, but I wonder how it would look in fact; the Lavenders are rather blah compared to the sparkle and jazz of SSH patterning.

Not if you use a leghbar hen... the F1 hens of your cross will be None barred but will carry one copy of the O(Blue gene) gene...
