Chick Down color

[gayle]

There is always a question on chick down color.
Here is a forum on the coop by some breeders who are well versed on genetics. They will take you on an interesting ride into genetics on chick down color. Pertaining to Locus and modifiers.

Now alot of your buff orpingtons are sitting on eb/eb with modifiers.
A lot of black orpingtons and white orpingtons are sitting on E/E with modifiers and enhancers depending on what color a person is working on.

now there are a lot of recessive white birds that are sitting on eb/eb like your wyndotes and white rocks. now if you cross these on to E/E whites, your birds may be sitting on 2 different locus, which are being modified by each other. So on and so forth.

I remember breeders talking about whites chickens who produce babychicks with red spots on their heads. A breeder put a picture of such a babychick on this forum

www.the-coop.org/forums/ubbthreads.php?ubb=showflat&Number=91532&page=all

this forum is loaded with babychicks showing their locus and what happens when genetic modifiers and enhancer are applied to these loci.

Dominate white on ER = notice the red spot on head.
