The "Ask Anything" to Nicalandia Thread

[NatJ]

So glad to see you're back, @nicalandia

Is this true?
An expert in a FB group said that to get Fibro from mixed breeding, the other parent has to have slate shanks.

As a sex-linked recessive, would all the sons of a fibro hen crossed with a white shanked rooster be carrying 1 copy of Fibro?
Or just some of them?
Am I better off crossing the fibro hen with a slate shanked rooster?
* for blue ears breeding, not super black skin.

@NatJ I would appreciate your input as well, if your computer is cooperating?

It looks like this has already been answered pretty well, but if you want the basic idea in my words too:

--Fibro cannot show unless the bird has the gene for dark skin (dark skin gives slate/willow shanks if the bird does not have fibro)

--Fibro itself is dominant, so crossing a fibro bird with a slate-shanked bird or a willow-shanked bird should give chicks that show fibro

--In mixes with light-skinned birds, you often get chicks with light legs, even though they do have the fibro gene. It just cannot express when the light skin gene is present. (Light skinned father produces light-skinned chicks of both sexes, light skinned mother produces light-skinned sons but does not affect the daughters.)

Fibromelanosis is the full form of the gene name. "Fibro" is much shorter to type, so I was lazy and used it.

@nicalandia do you have any sources (studies or something) that explain what a chicken with a simple E/E genotype would look like?
I believe this would be a rusty black phenotype but my friend thinks it would be solid black. I pointed out that this is Henk’s opinion and the general consensus but she wants a source since she found a study with the exact opposite opinion. Unfortunately, I tried viewing this study and could not because of paywalls. I haven’t been able to find these studies or figure out how people decided that a black with no additional melanizers would be rusty black.

How is this even for Debate? Melanotic, Charcoal, recessive black all have been discovered on Black Breeds, the most powerful Melanizers have been discovered on Black birds. If you were to isolate Extended Black all by itself it would be a Dark birchen males with mostly black females

Over The past 100 Years Researchers have found all different types of Melanizers in Self Black birds, Recessive Black by Dr. Punnett, Brassy Back on OEG. Melanotic in Minorcas. Why would self black birds carry so many of them if not to make them completely black?

I have no barred adults, but a 5 week old home bred chick looks barred. @nicalandia can you please explain to me how this happens? Or is it not real barring but some other pattern? TIA

It's autosomal Barring. You got Db, Pg and Ml at least one copy of each. What are her parents?

Thank you. I think her mum was the daughter of a partridge Penedesenca roo over a Swedish Flower hen. Her dad could have been any one of 3 hybrid roos all with the same sort of heritage (including SFH roo over PP hen) or the son of a PP roo over a Lavender Araucana hen.

At this stage she resembles a Silver Campine Pullet, could change later due to variables

yes that's what I was thinking, or a silver Brakel.

I've made many crosses of black varieties to wildtype, which were always followed by successive backcrosses to wildtype. In every case, many of the second generation e+ chicks are melanized to various degrees. I have also isolated one gene that is recessive and strong enough to darken the secondaries in e+ males.

Wing bow or wing bay?

Got this girl out of Dusty an EE bantam rooster that looked to be Golden blue duckwing and a silver Phoenix hen.

Dusty

One of Dustys daughters.

Alot of his offspring have the dark heads. I suspect he may be berchin as well. A few of the offspring females look silver berchin.
