-------------------------------

The first three books are mostly up-to-date, but there were some changes in secondary pattern genes, etc after books 4, 5 & 6 were published.
Some of the out-of-date genes listed in Dr Hollander's book are:
I is listed as "Pyle", but generally called "Dominant White" today,
Gr (Ginger) = Columbian (Co) today,
Nigrum = Extended Black (E) today.

Ab, Lg & Sp are now obsolete (genes Pg, Ml & Db are used instead).

Not all of the E locus alleles are in these books (especially the Hutt book).

So it's best the read the most recent books first ( ie 1, 2 & 3), &/or compare to the genes table at the Sellers Website. There is still plenty of good information in the old books though

------------------
There is a recently published poultry genetics book:

Muir and Aggrey (ed) (2003) Poultry Genetics, Breeding and Biotechnology CABI Publishing.
but this one doesn't have a chapter on plumage colour/pattern genetics. There is information on genetics resistance breeding, etc.

Hartl, Daniel L.
A Primer of Population Genetics
ISBN: 0878933018
(not information on poultry colour/pattern genetics)

(1991) Genetics and Evolution of the Domestic Fowl
by Lewis Stevens

* very little information on colour/pattern genetics

Dr H.S. Gankema, VERERVING VAN VEERKLEUR BIJ HOENDERS (Inheritance of Feather Color in Chickens) .

Morley A & Jull (1932). Poultry Breeding.

There is a whole Poultry Genetics (& poultry evolution) book online, but all in Italian. It is more recent information than "Poultry Breeding & Genetics". Here is the website:
http://www.summagallicana.it/

• Volume 1: Origin of the domestic fowl ( including a chapter on Araucanas)


• Volume 2: Genetics theory, etc (including a large section on population genetics)


• Volume 3: Alot of information on colour/pattern genes (plus plenty more topics).

*The genetics information is in volume 3 (includes links to photos)
