    The rooster shown below is from an accidental crossing of an OEGB rooster with a buff silkie hen. It can clearly be seen that he was WHITE skin and not the dark skin usually seen in silkie mixes. This is him:
    [​IMG]

    I mated him back to pure OEGB hens and got this hen, who is technically 3/4 OEGB and 1/4 silkie. Her black skin can clearly be seen. How can she have black skin if both of her parents have white skin? Is this possible? She also has a straight comb unlike her father. Could a pure silkie rooster have slipped in and mated with the OEGB hens, making this hen half silkie half OEGB?:

    I then mated the hen showed above back to a pure OEGB Rooster and got these chicks, all light skin and looking very much like OEGBs:

    So in conclusion, in order for the mixed rooster at the very top to have sired the hen shown in the middle picture, the dark skin had to have been hiding somewhere in the genetics. Is this possible? Or did I mess up along the way and let a pure silkie roo in the pen?

    I can't answer your question, but I have to say that rooster is a beauty.

    Quote:well I can and I am going to do just that... ok Friends, Fibromelanotic is a Dominant gene, which only means that Fm is dominant over its wildtype counter art fm+, BUT..... it needs sex linked id+( responsible for blue/slate shank o white skin birds or green/willow shanks on green skin) What this means? it means that when Fibromelanotic is in the presence of Id(responsible for white shanks on white skin and yellow shanks on yellow skin) it will not express the black skin or or black shanks.... BUT... there is always a BUT... that rooster of yours had id+ hidding on him(he was Id/id+) and since id+ and Id are sexlinked it means that 50% of his Pullets will inherit the id+ and Fm(Fm is not sex linked) genes at the same time making this pullets sired by him have black skin and dark shanks... now you all can thank me now... :)

    why did the OEG x Silkie hen cross didnt produced black skin pullets? well they could only iherit the Id gene from their OEG father thats whay..


    id+ plus Fm is such a great combo that it can be use to create Sexlinks...

    Cross ANY Silkie rooster to ANY, ANY hen with yellow/white shanks and you will produce visible Sexlinks, the pullets from that cross will produce Black skin pullets that you can see since hatch.. and males with yellow/white shanks..

    I've done this (fibromelanotic rooster x white leghorn pullets) 100% Sexlinks

    I wish I could digest and understand this...
    Id is 'dermal inhibitor'? And Id is sex-linked.
    I don't get it completely, but I did just have a *brief* moment of clarity that explained some things : )
    What breeds do not have Id?

    birds that dont carry Id(dominant sex linked Dermal inhibitor...yeah long word) are birds that have slate/blue shanks and birds with willow/green shanks or birds with dark/slate shanks... birds that do have yellow or white shanks


    so birds with Fibromelanotic with Id will have yellow/white skin and shanks, birds with id+ and fibromelanotic will have black/blue skin..

    This is somewhat confusing to follow, but I have a dark-skinned EE rooster. Mother was an EE, father was an OEGB/Silkie (could have been different generations of this cross, probably had light skin). Could I create sexlinks with this dark-skinned rooster?

    So would a silkie roo x turken hen create sexlinked chicks?
