Please stay . . . we really are trying to encourage more people to get involved with LF. I would, but I just don't have the coop space. And there really is a lot discussed here that applies to both bantam and LF.

This is the outline of Brian Reeder's book I did a while back: Kind of lengthy, but scroll down to the middle and a bunch of color varieties are listed under the specific alleles.

The Genetics of Color and Pattern (Brian Reeder):

Melanin (pigment) – two forms:
Pheomelanin (red pigment) – two types:
Autosomal
Sex-Linked
Eumelanin (black pigment)

The E-Locus:
e+ Wild type or Duckwing
eWh Wheaten
eb Brown
ER Birchen
E Extended Black

The order of dominance in the e-allele is: E->ER->eWh (without melanizers present)
e+->eb->eWh (when melanizers are present)

The Gene List:

Diluters which have a greater influence on pheomelanin:
S – Sex-linked Silver
ap+ - Absence of Autosomal pheomelanin
Di – Dilute
Cb – Champagne Blonde
ig – inhibitor of gold
Diluters which have a greater influence on Eumelanin:
I – Dominant white
Bl – Blue
Id – Dun
“rc” – recessive chocolate
Diluters with an equal effect on both forms of melanin:
lav – lavender
Intensifiers of Pheomelanin:
Mh – Mahogany
Extenders of Pheomelanin:
Co – Columbian
Db – Dark Brown “ginger”
Extenders of Eumelanin:
Ml – Melanotic
cha – charcoal
“rb” – recessive black
Genes removing all pigment:
c - Recessive white
Feather-pattern modifier genes:
Pg – Pattern gene
B – sex-linked Barring
mo – mottling

Composite Combinations:

Wild type or Duckwing (e+) – chick down is chipmunk striped; aka agouti (when not affected by other dilution or enhancement genes)
Wheaten (eWh) – chick down, in general, tends to be solid white or yellow or pale orange, with no patterning
Brown (eb) – chick down has the greatest variation of all alleles; the basic eb s+ chick is quite like the e+s+ chick, but they are more diffused in their striping down the back; difficult to determine this allele by chick down alone
Birchen (ER) – chick down, in most instances, is black with a reddish head, even when S is present
Extended Black (E) – chick down of this allele is black and marbled on the undersides with yellow to white

I was a biology major in College (and did very well in genetics class) but Chicken genetics is WAY complicated! Makes my head spin for sure! (Now I am a very happy, "starving" musician who also happens to have a few chickens in the back yard!)

In 08 was lucky enough to get from Karl and Norman Rau my start in Cochins! I have kept the line pure, and have shown and won with their birds.
They were after 35 years were done asked them to send me there very best They did!!!!!!!!! blue, black, and Splash and Mottled.

Just so that I'm not steering someone wrong - I really need to clarify. I am NOT a Geneticist . . . I'm just trying to study and learn along with the rest of you. As I said, that was nothing more than an outline I did a year ago of Brian Reeder's book.

In my real life, I'm a Bean Counter/Accountess - OK, my official title is General Ledger Manager. I spend my day spewing forth financial statements - P&L's, Balance Sheets, etc.

A couple of years ago, I had two white Silkie hens - I couldn't tell one from the other. So I named them Debit and Credit. After that, I was always able to tell them apart - whenever I looked at them, Debit was always on the left and Credit was always on the right.

I hope I haven't mislead anyone. ~Gail
