how do you get blue partridge?

[Goose and Fig]

Just wondering- is this a cross, or a color in it's own right? How do you make it?

It's not a cross. It is gold pattern gene bird with a blue gene.

You would need to cross to a bird with a blue gene to get the blue gene & cross the offspring back to partridge.

Depending upon the bird you use to get the blue gene, there would usually be other genes to breed out, but that's the basic method.

so- Blue or splash X partridge?
Or Blue X Partridge, then F1 to blue?

Blue or splash X partridge

Yes.

Then blue F1 to partridge.

Will the color breed true- or is this a one time deal?

It will segregate as andalusian blue usually does.

When I breed blue partridge in silkies I did blue roo to partridge hen. The coloring is spread out like a splash but it had the partridge and blue colors. Some of the hens had very dark blue almost black and some had more of the lighter blue. When I crossed a hen bred like this back to another blue I lost alot of the partridge color. I actually gave those chicks away as mixes because although their type was excellent they were too dark. I am not a genetic expert though so..that was just my experience. LOL
