How many have we observed in Icelandic chickens? So far this is what I have seen in pictures.
eWh -Wheaten
e+ -duckwing
ER - birchen
possibly, E-extended black?
Please correct me if I am wrong, and with any other E locus(s) you have observed.
There is also a possibility that many of the Icelandic E locus are different forms than that of other chickens.

Ryan, this is great! You are a great observer! How all this works in Icelandics is very different than in other breeds, and I really don't understand it. If we take our standard chicken genetics, you can get a pretty standard out come of crosses. Not so in Icelandics. So do we really have what we see? What of masking genes? And can a gene such as a simple black gene which is dominant in other breeds possibly be recessive in Icelandics or are we looking at a totally different combo of genes? Its u puzzle Ryan! But I am excited about your post and observations, with a mind like yours, you will be a great asset in pioneering research in this breed! What a resume when you are my age, "Began researching Icelandic Chicken genetics at 14 years old!" Amazing Ryan! Thanks brother! AndyfromFredericksburg

Ryan, I have a request for you. Would you like the honor of teaching our Icelandic Preservation Society of America a little about genetics? You and I could shoot notes back and forth but I learned on BYC that people who don't understand the terminology feel like outsiders in the discussions. You did such a great job presenting your observations that you would be a great help in explaining things to folks! Would you mind? Of course being homeschooled you won't want to let this interfere with necessary duties and it would be great to include your parents in this and have their blessing as well as permission. Maybe it can tie into some aspect of your schooling as well? Andy

Thank you for the honor, whether I am the right person to do so is another question. I will definitely be able to help more after I have done a good share of breeding them.
As far as black, I think that black Icelandics can be explained by current genetic knowledge. For example, the rooster Icee is most likely a birchen or extended black split to duckwing with dominant white. When crossed to a duckwing hen, half would inherit birchen or extended black(whichever one he is) and half would just be duckwing. Also half would inherit dominant white. The females that did not inherit dominant white but inherited ether birchen or extended black would likely appear mostly if not all black. The males would have some red in their shoulders, neck, and saddle.

Amazing young man! I got it! now to record this, test the theory and see if it plays out. What are the possible progeny of any of these crosses Ryan such as two extended black minus dominant white? Andy

If two extended black/duckwings are bred together 25% would be duckwings, 50% duckwing/extended black, 25% extended black. However, The black males (especially the impure ones) would have some red or silver leakage I think.

As far as other color genes, this is what I have seen in pictures:
Co-columbia
Db-darkbrown?
Ml-melanotic?
Mh-mahogany
possibly ether dilute, inhibitor of gold, or champagneblond?
S-silver
I-dominant white
Bl-blue
Mo-mottling
Please let me know if you think any genes should be added or removed.

As far as columbia, do any Icelandics in the USA have it? If so I have not seen any pictures of them.

Ryan. One man claims to have an understanding of some of these Icelandic genetics and he tells me that he sees the Columbian in his flock. I haven't seen this yet. It certainly doesn't mean it's not there just because i haven't seen it though . Thats the great thing about these Icelandics, so much mystery! AndyfromFredericksburg

Wow! You guys are something else! My head's spinning. Would it be possible to post pictures illustrating the variety of colors, characteristics, etc. so we have some idea of what we are observing in our own flocks?

Cindy, I would not be able to due this due to my small young flock. Maybe someone else could take this up? Or we could post pictures of other breeds (crediting the owner of course) to use as examples. This calculator is great for showing the various affects of genes : kippenjungle.nl/kruising.htmlAndy, It would be great to see some columbians. I also read somewhere that barring also exists in some Icelandics, but I havent seen any pics to prove this yet.

Thanks Ryan! It took a lot more time for me than for a computer expert. Those are all taken with my phone camera! Andyfromfbg
