    I don't recognise the breed, but those are lovely hens. Their brick shape reminds me of RIR but they obviously are not RIR. Since the picture is labeled US Agriculture, I would say they are possibly hybrids or some commericial variety. I hope some one will give you a better answer.

    Thanks for your help.
    I really do like their plumage, I would like to find a resource for more information about them and possibly where to purchase these beauties.


    If you don't mind, could you please spell out eWh/e+ hens with Co/co+ Pg/pg+cross breeds?

    Thanks again :)

    well let me try, I´m not really that good of a teacher...

    e+ is the wildtype(wildtype because it was found on the "wild" Red Jungle Fowl) e allele. there are a few mutations on the e allele but to keep this as short and concise we will talk about e+ and eWh Only....

    eWh is the "wheaten" e allele mutation, this mutation is incompletely dominant over the wildtype(e+) allele, meaning when you have a bird with e+/eWh genotype you will have a bird that will have similar traits as both genes..

    this is how a wildtype hen looks like without any other gene modifying its phenotype(looks)

    now to the modifying genes, Co/co+. Co stands for the Dominant Columbian like gene Columbian.(Co) co+ stands for the wildtype counter part(co+) Columbian restrict the hens eumelanin(black feathers) to the tails and to the neck hackles of the females,

    this is how a Columbian restricted hen looks like

    now why if the hen is restricted by Co does she has some markings on her body? you can thank Pg for that.. Pg stands for Patern gene, which is dominant over pg+ which is its wildtype counter part...

    one copy of Pg can do this

    chick how it says, Pg alone results in a black tip. source http://chickengenetics.edelras.nl/

    the hens may or may not carry Pg, it could be other melanizers, but Co/co, she centrainly has

    Well, that is a lesson in genetics! Very well explained but much too deep for me :) Thank you for your time and thoughtful effort. As a Simpleton, I would like to find a breeder/supplier that can provide these beautiful birds for my small home flock. Again, thanks for answering my question accurately.

    the cross you just described its very similar to the black sex link cross hatcheries do, a Wheaten(both buff orp and RIR are wheaten eWh based) Columbian(both Buff Orp and RIR are Columbian Co based, Buff Orps have other restrictors as well but they dont work very well on Extended black birds)

    the black sex link hen above is E/eWh(E from Barred rock hen, and eWh from RIR) Co/co+(Co from RIR and co+ from BR) s+/-(s+ from RIR sire) a Buff orp rooster mated to a BR Hen would produce a very similar bird as the black sex link hen
