I think that my wrong use of terms to reffere to the OEGB have created some confution. Thats my bad. Acording to what I can see, must people agree that the bird loock like wheaten in color and the legs are slate. Is not that I'm trying to get a bird with black or darck legs, the problem seems to be that I used this terms(black, darck) to reffer to what seems to otherwise be slate. Taking this into consideration, lets start fresh. I want to take this wheaten, slate legged bird, and make him a female of his own blood wish I dont have. Acording to Mendel's laws this is possible. If I use a hen that look like him, it will be virtualy impossible to determine which chicks are of the blood of the cock because they will look the same. If instead I use a hen different in color, it will be easier to tell which ofprings are of the cocks blood and which are not. Using mendel's laws let say that D= is going to stand for the wheaten color of the cock which should be dominant. d= is going to stand for the white color of the hen which should be resecive. s= is going to stand for the slate legs which should be resecive and S= is going to stand for the yellow legs of the hen for the purpose of this hipotetic example.

Now; we have that the cock will be -DDss- and the hen will be -ddSS-. When you breed them, the ofprings(F1 generation) should come out wheaten and yellow legged in aparience( I already know OEGB do not come with yellow legs, this is just an example) since this are the dominant trates, but with the rescecive genes for white and slate legs not vissible, so they will all be -DdSs-. Now, if I take this ofpring and breed them brother to sister -DdSs- + -DdSs-, the ofprings of this union should give me several different convinations from wich I will use the resecive trate(slate legs -s- ) as the indicator, since resecive traits are always homozygous(pure), so, basicaly I will pic up individuals that are wheaten with slate leggs to line breed back to the line of the original cock -DDss-. Now, this individuals that I will shose will be in part heterozygous for white -Ddss- which means that they are going to be wheaten with the white gene inside; the rest and least, will be homozygous(pure) wheaten wich is what I,m looking for. When I line breed this selected individuals of the F2 generation( -Ddss-, -DDss- ) back to the original cock( -DDss- ) The individuals of the F3 generation will tell me which from the F2 generation are pure wheaten( -DDss- ). the ones that produce white slated legs birds( -ddss- ) as part of the progeny will be impure, I will descard them. The ones from the F2 generation that only produce wheaten slate legged birds should be pure ( -DDss- ). This I will continue to line bread back to the original cock( -DDss- ) and should always breed true to color. Thats the reason I'm looking for a dominant leg color in the hen to be able to use as an indicator. It will be much easier if the leg color as well as the feather color of the hen are clearly dominant over that of the cock; resecive traits always breed true and are easier to identify, but I dont know if there is a clearly complete dominant color that can overpower the wheaten color.
Hope you all are able to understand all this mess.. I my self have a headace already . Maybe I'm complicating my self to much .
The bird is muffed and now I'm more puzzled by TomNY saying it is a Dutch and not an OEGB. It was given to me as an OEGB. How do I know the difference ??
I apreciate your opinions !
