Dhia Dhuit Sumi !
Thanks for sharing.
We all know that the Icelandic Chicken we love has been isolated for a long time. But, we don't know just what we have. Other then their beauty and great ranging and surviving ability.
For example the Jungle Fowl has a gene SB 2 that strengthens hardiness and resistance to diseases, Mareks for example. There are some 'modern' breeds that have lost it. Does the Icelandic have it? I don't know, and I don't know what other genes it has.
I know they are hardy, good brooders and can range very well. But what else?
I have posted in the past that I myself want to see more crests, tiny combs, few wattles and well feathered legs because I believe that each of these can contribute to winter hardiness. I have seen my beautiful roosters with big combs get frostbit here in our MI winters. So for me its selection within my stock and others for these traits. Folks in warmer climes don't need them, while folks up here can keep them buttoned up tight in cold weather.
But what are these genes that control these ? What genes are hidden that we don't know about that contribute so much to the breed?
I'd really like to know, a number of other breeds have been studied and we are beginning to know their genome, we should know how our breed differs from the Red Jungle Fowl and what it has in common , and with other breeds.
In the meantime I will just enjoy them.
