Color genetics thread.

[Amy King Hanson]

I produced a number of birds like her. They produced a light blue egg that was smooth- like a leghorn egg but light blue. The eggs were not blue enough so I stopped the project. This is another bird I was producing (I was hoping to produce additional plumage colors) . I liked working with dominant white so I would produce a white bird first. This is another bird I produced ( she also had a sister like her). It does not have white skin but is barred and mottled and lacks a crest. I was going to use it to breed with my whites. This would have produced some crested offspring with white skin with white plumage. I would then do a back cross to produce prototypes of the birds I wanted. The trouble was that I did not have enough cash and facilities to finish the project. Facilities was my biggest problem and I did not want to shell out 25,000 to build the facilities. I will be moving from my place in a few years and would rather have the barn on my new land.

Sounds like great goals!! The reason I asked about matte vs satin in because of these two posts that I saved.

This one I finally can see the difference when a CL is crossed with a brown egg layer. I seems the CL hybrid green eggs are duller than a Ameraucana's hybrid green egg. I'll soon find out first hand. I have a project going with my CL rooster.

Gorgeous birds!!!!!!!!!!!!!!!!

Question out of curiosity. I'm far from being able to do this, but my mind gets ideas & curious......

I've a black crested white polish that is heavily marked from whatever the mix is used to get the black crest. I know it's a project color, etc. I love how my pullet looks. What I was wondering is how would you go about keeping the black, but having the white feathers be blue? Is that possible? Would it be primarily line breeding? I realize I'd probably need more like her, if it's an issue of crossing her with a blue roo....in polish I don't know if a black crested blue, just the white crested blue. If using that type of roo, which would dominate the black or white crest? Or would need to bring in a self-blue from a different breed/variety? If so, which? Do you look for a breed/variety close to the body you want (skin, leg color/feather, etc) or for another reason?

Thank so much for the patience & time! I'm learning, even by the stuff that's ahead of me.

This is her:

After I started the project, a few papers were published concerning the anatomy of pigment deposition and biochemistry of the pigments that produce a blue egg shell. I also did not do enough research on the subject before I started the project. If I had, I would not have started the project, Read the following post and white paper. If you have questions about the white paper feel free to ask.

This is her:

I am sorry to say you are stuck with the white. The sex-linked silver gene is causing the white color and there is no gene that can change the white to blue. The blue color in chickens is due to genes that are classified as diluters. They dilute black to blue. The black in your bird can be diluted to blue if she carried certain genes but the white can not be changed to blue. A single blue gene normally has little effect upon the black in the hackles but will dilute the black in the spangles and the black markings in the feathers. The color of the hackles is normally darker than the rest of the bird. Sometimes the hackles are black and other times the black is somewhat diluted.

The two common genes that cause the blue color are autosomal recessive lavender and the autosomal incompletely dominant blue gene. The black crest on your bird is most likely due to to the autosomal incompletely dominant melanotic gene. She is also carrying some of the genes for spangling. She carries two birchen alleles, two melanotic and most likely only one pattern gene and one dark brown gene. She should have two of each of the genes I mentioned.

Normally two dark brown genes clear the black from the head and neck of the male chicken and sometimes it only takes one depending on the genes in the bird. In females sometimes it does remove the black from the neck hackles but most of the time females will have black and white in the hackles ( silver birds).

If you had a blue polish rooster and crossed him with this hen, (if you hatched enough chicks) some of the chicks would be blue and white with similar blue markings.

I believe she is a black crested white and spitzhauben hybrid.

Looks like she's mixed with one of these.

Or the brabanter it's similar with a black crest. That bird looks neat too!

Thank you. I appreciate the explanation & you sharing your knowledge. I know I've a lot to learn. It's amazing you can tell all that from the photos!

She's from Ideal....part of a crested special the feed store had gotten. I went researching & found a black crested white polish (project they noted) on their site. At one point I thought she might be brabanter, but that's not listed as their cresteds nor do they list the black & white one.

I was just curious if it's possible to created I guess essentially a blue spangled polish it would be?? Though your thought on blue & white with similar markings could be interesting. I don't have a blue polish of any sort (though I only know of white crested blue). However, I do have a blue cochin bantam. I know totally different breed, but if color genetics carry regardless of breed I might get really fluffy polish/cochin crosses with that look. Hmmmmm.....it's a free roaming backyard flock so could happen.

For now, no plans to hatch/breed except for the crevecoeurs as I'd like to keep them going & get back to what they should be & if I can get a good roo the self-blue cochins. First, I'll need separate pens & them all to grow up a bit more. They're 6months & 3months.

If I crossed the hen that laid this with a true Ameraucana, would the females that hatch all lay spotted eggs? Would they have less spots or about the same amount. The rooster I plan on using is a black Ameraucana with red leakage, so no spotting genes will come from him.

I can tell you why the spots are there but I have never read any research that deals with spotting on eggs in chickens. Other birds are genetically programmed to produce spots on eggs, strips on eggs, etc.- one can identify the species by the eggs they produce.

Here is a picture of what I am posting about.
