Dun, Khaki, Platinum?

[EnnieM0097]

my brain is fried, trying to understand these genetics. is this correct? can anyone share photos? I'm breeding specifically with silkies and satins, but any pics help.

dun x dun = 1/4 khaki, 1/4 black, 1/2 dun
dun x blue = 100% platinum

You are correct on dun x dun. It behaves like blue x blue in that you get 1/4 black, 1/4 double dose of the gene (khaki from dun or splash from blue), and 1/2 single dose of the gene (dun or blue, respectively).

Dun x blue is different, though. The genes are independent of one another, not allelic. Your offspring have a 50-50 shot of inheriting a dun gene from their dun parent, and independently another 50-50 shot of inheriting a blue gene from their blue parent. Crossing the two together gives you the possibility that they inherit both genes, that they inherit dun and not blue, that they inherit blue and not dun, or that they inherit neither. Each option has equal odds, giving you a 1 in 4 chance for any of those outcomes. So in other words, your offspring from blue x dun should be about 1/4 black, 1/4 blue, 1/4 dun, and 1/4 platinum.

Edited for a typo ​

Yes, exactly.

Also, khaki x black = 100% dun

If you want 100% platinum, cross khaki x splash. That way every chick inherits one dun gene from one parent, and one splash gene from the other parent, so they have exactly the right number of each. Or crossing a bird that is splash & khaki (whatever that's called) with a black bird will also give 100% platinum.

New member hoping to revive an old thread here! Photos of my 3 Olive Egger hens that I believe to be platinum (but khaki-ish?), platinum (but with some darker feathers -- maybe platinum splash?), and dun are attached. These hens are about a year old and colors have lightened a bit recently. I would be grateful of someone could help me understand what feather colors are possible if these hens are bred to a black rooster.

Very pretty I'm following because I'm interested.

Do you know their parentage?

My hens are from a breeder who has posted on this forum, but not recently. I’ve reached out to reconnect and get more information. If I recall correctly, these hens were sired by either a Black or a Blue Marans over Ameraucana-type hens that may have also had some Marans breeding.

To add: The breeder had hens that were outwardly similar in color to the hens in the photos.

The first two hens do look khaki and the third looks like a dun, I’m unsure if they have the blue gene or not

Thanks, RAR! I have eggs from these hens that were bred to a black rooster in the incubator. Hoping for some khaki and dun birds.
