Hmmm. Didint thinkof that. I think the 'breed' was/is very isolated in Iceland and the original birds were imported fairly recently in to the US. The eggs I recieved are 2nd generation of those birds. The original birds were from a flock in Iceland that has had no other blood introduced in many, many generations. That to me sounds like a breed.
So, if a 'breed' comes in more than a few colors, it isnt a 'breed'? They do lay uniformly colored eggs. They simply have enough varied genetics to be able to produce a multitude of colors and pattens. I guess it might make them more a 'wild' strain, or 'breed' , like jungle fowl?
Of course, there are many color variations in many breeds and they are still acepted as breeds, why not these? I dont see why anyone could not simply decide they like a certain color/comb and continue to breed for those colors and designs, and still be able to call them the same breed.
I think its just a hard thing to accept that they really are diverse and there is not a specific standard (other than eggs and true genetics) to hold them to. I dont have any idea if they are showable or even considered a breed by the SOP people.
I know I like them, and I know what I've read and been told, so I only can go by those things. Anyone who might be interested can easily do a google search, and they will find Icelandics clearly described as a breed.
