Experience breeding with dominant white anyone?

[Steinagarden]

I am looking into the gene of dominant white to remove the black I dont want. I see that chamois is a dominant white that breeds true. And I guess, based on what I have read so far, as long as you have a really strong Mh and Db the dominant white should not affect the ground colour too much then you are working on a buff colour. I also know that I need to breed back to a darker buff chicken without dominant white from time to time to keep the ground colour, I dont mind that. Its more important for me to not have the black.

I am using Buff Colombian and would like to consider dominant white to remove the black. My end results would wanna be a buff barred colombian without any black in a pure buff even colour.

I have Lohman brown that I think could be both homozygot and heterozygot for dominant white. I have both almost completely white birds with minimal red leakage and some that are more very faded buff/wheaten. None of them looked greyish as baby chicks and there is no silver, so I dont think there is any chance of recessive white.

I also have some that have some black feathers, is it safe to say that any chicken showing black is not a dominant white? But if I see both white and some black it could still be heterozygot dominant white? Will there always be sign of white feathers when there is dominant white?

My big question is; has anyone experience breeding with dominant white to remove black leakage and keeping a good ground colour? How hard is to get there?

I am considering mating a buff colombian rooster over my Lohman brown, also using the white ones which could be homozygot, just to see how the results end up and how the dominant white works when I use a male that are buff Colombian.

Photos to show some of my Lohman brown. I have all "shades" from white to very dark red.

Hi,

Seeing your post sitting here a couple of days unanswered, I'll give it a shot.

I don't know if this article helps you at all but it seems to cover the dominant white aspect of breeding:
https://poultrykeeper.com/poultry-breeding/dominant-white-gene/#:~:text=At present, it appears the,'Hamburgh-Pencilled' fowl.

The only thing I know is that with silkies, we can get a dominant white from breeding two paint chickens together. They produce 25% black, 50% paint, and 25% white without paint, being dominant white. The dominant white can now be bred to any black chicken and produce 100% paint. That's my goal, but I'm at the first step this spring.

Those are cute chickens btw!

Thank you, I was hoping for more replies than this

I read the article, thank you. Regarding paint this is quite a different colour than what I am using and why am I am interested in dominant white.

Dominant white removes/turnes black into white. So a dominant white chicken who is white all over, is actually a black chicken. Paint I guess is heterozygot for dominant white.

The gene is leaky, so some black can get through. I want to breed it in homozygot form. I want an buff chicken with no black, but as the dominant white has some effect to the buff colour, I was really keen to get advice from someone who as worked with this colour varierty before.

I have seen White Laced Red Cornish, with a rich red ground color and the Dominant White gene (presumably homozygous, given that they breed true.)

"Buff Laced" Polish have white lacing on a gold ground color, and they also appear to breed true. I haven't seen them in person, but I've seen plenty of photos.

You can probably get birds homozygous for Dominant White, breeding true for a gold shade or a red shade depening on what other genes are present. Presumably you could breed from the ones that are closest to the color you want, and make progrees toward having more of that color.
