John,
You posted while I was writing so please excuse me for repeating the information.

Glen,
There are a number of different books that have been written on poultry genetics.
One is : Genetics and Evolution of the Domestic Fowl by Lewis Stevens (1991)
You can get a used paper back version of this for under 20 dollars.
Another is : Poultry Breeding and Genetics (Hardcover)
by R. D. Crawford (Editor) 1990
This is a very good book but is not cheap (200.00). It may be out of print.
Another recent book is An Introduction to Color Forms of the Domestic Fowl: by Brian Reeder (Paperback - Feb 8, 2006)
You can get a used book for around 20 dollars.
Reeder is not a professional scientist and sometimes makes statements that I strongly disagree with. He does not follow protocol that is acceptable by the scientific community.
Do a search and find the cheapest vendor.
A good site to go to is
http://marsa_sellers.tripod.com/geneticspages/page0.htmlI did have a site but the server erased the site and I did not back up my work.
To discuss genetics on a form, you can do it here or another site would be The Coop
Register at the following site and then go to the forum home and Genetics and Breeding.
http://www.the-coop.org/cgi-bin/UBB/ultimatebb.cgi?ubb=agreeI would suggest you learn as much as you can about the E locus then go from there.
You can do a search on The Coop forum and can find all kinds of information that will answer your questions. Dr. Ron Okimoto is very knowledgeable and a professional scientist. There are also others that are very knowledgeable.
If you want to find papers or abstracts from scientific journals use Google Scholar or use
http://www.ncbi.nlm.nih.gov/sites/entrez and query an authors
name. Start with Carefoot WC, Campo JL and Smith JR Jr.
That will keep you very busy. If you have questions post them at the ABC forum and I and others here will help you.
Good luck
Tim
