Interesting discussion here, typing on a forum is an inexact medium so I have to remind myself often to cut slack instead of shooting first and asking later, as some may recall,
Centrarchid brought three very major points up on the directions most people on this forum have, and I think most of us agree that the folks on this thread are major concerned with preservation of the Icelandic Chicken as a resource of rare and unusual genes. We also have a ball watching and interacting with our chickens, I know that I do, every day !!
Thats a big reason why we all are concerned about maintaining the purity of our stock, they truly are an unknown quantity genetically, Iceland is a small country with a small science ag center, and they are the ones I give the most credit to, so to be doing any crossing with them is to contaminate a very unusual and limited gene pool. There is a great deal that we dont know, and the knowledge is going to come out like peeling layers of an onion, a bit at a time. There isnt going to be a big mass of info dumped out at one time. Its going to take time and study.
When I first read of them, here on this forum I was immediately fascinated with them. Being isolated as long as they were is itself unusual, there are older breeds in the world, but, those have been continually exposed to other genetics added in, the govt of Iceland has been very strict against letting any other imports into the country for hundreds of years, a great many of the breeds currently in the American standard only date back to strains of the early 1900s. The Icelandic was at that state a 1,000 years before !
Eventually we will know what the close timeline is, until we do know differrent I accept the 800s-900s as their likely introduction to Iceland by Norwegian settlers.
Having read and enjoyed the Iceland sagas, and those of Norway I know a little bit of life back then, it was hard, cruelly hard, nothing we in our cultures can remotely relate to. I am fascinated at a Breed/Landrace of chickens that could survive in a country that had very little grain production ! How many of our current modern breeds can do that ?
We are just beginning to crack open the door to peek in at this Chicken that fascinates us so much. I know that inevitably we will exert selection pressures, I myself prefer rose combs, so, to guard against losing another trait I am keeping a SC roo also. I am trying to keep multiple different roos to breed on a flock basis to keep as many of the genes that are in my flock as I can, while also starting other interested folks with them.
The learning about the Icelandic Chicken is probably going to take many more years then I have, but, in the meantime I am going to enjoy learning what I can and sharing it with others. I know of several other traits that I dont have, and hope to add next year. And by then I will probably be looking for others. Its a long time thing pursuit, just of finding out what we have.
Time to go out and hobnob with my friends of the cluck persuasion.
Life is good ! And Better with Icelandic Chickens and Goats !
