The "Ask Anything" to Nicalandia Thread

I bred a pure light Brahma hen to my light Brahma roo who is split buff Columbian and got a light color buff looking chick. This may be a stupid question but wouldn’t that mean my pure hen is also split for buff or is there something else going on?

Sex-linked gold/silver gene is causing this.

The rooster has sex chromosomes ZZ. He has silver on one and gold on the other. He gave a Z chromosome with gold to this chick.

The hen has sex chromosomes ZW. The Z has silver on it (so she looks silver) and the W chromosome makes her female. She gave the W chromosome to her chick, which means the chick is a female.

The hen will give a Z chromosome to her sons, which gives them the silver gene, so all her sons will show silver.

The rooster will give one Z chromosome to each chick, with some getting the Z with gold and some getting the Z with silver. For daughters, that means some will be silver and some will be gold. For sons, because they also inherit silver from their mother, they will either be pure silver or split silver/gold, with all of them looking silver when they hatch.

(Unless this is a silver chick with an extra amount of yellow in the down, which I do not think is the case.)

Thank you!

So would the split boys develop gold leakage when they get older like their dad?

Thank you!

You're welcome!

Probably yes.

The beige color is autosomal red and the eyebrow color is still the chick plumage which hasn't melted out yet.

thanks. Can I follow up with what turns autosomal red into beige? I've got a lot of chickens with red, but none threw this beige colour before and I'm really stumped. (Chicken genetics is challenging.) Is this smoky?

No it's not. Smoky is a rare gene that turns black into grey.
Autosomal red is beige on silver birds.
I think there is more than one gene that causes autosomal red. There is the autosomal red gene and then there are silver hens with brass despite the fact that their male counterparts don't have it. Like this hen or silver Phoenix.

For example, a totally brown silver phoenix

Hypothetically how would this particular color of Oxford OEGB be recreated?

 

[Amer]

Take brown red (red birchen) OEG and select for dark skin, deep red necks, and no breast lacing. This color already exists in Old English and I think it just comes down to selection.

Ok. Yes from what I have found the color does exist in OE (Along with Red Plye, Dark Penciled, but in the US the only Oxford verity available are ginger reds rom GreenFire Farms.

So He’s basically a brown red selected to have darker skin?

Same as a brown red Modern Game.
