Gosh~~I hate that I'm sooooo far behind on this brand new thread !!! dag-gone weather still hasn't really cleared up
Pennie~~your ponderings about the different "color" Partridges~~ideally, we should be breeding for the color explained in the SOP. Since Partridge is a very difficult color to perfect, you end up with alot of "off" colors that are still very beautiful. Those off colors are labeled by individual breeders, i.e. buff partridge, wheat partridge, etc. Those off color Partridges can still be shown as AOV.
Just speaking from my experiences with the shows I'm able to attend in my area---some judges don't even "like" to judge Silkies....and when it comes to the Partridge color, they're really thrown for a loop. So, even if your Partridge is not the perfect color (as stated in SOP) you can show them as Partridge, and if there are not other Partridges of correct color, you can still win. I have a couple that are not the ideal color, but wonderfully typey---I show them too.
As for blue---I don't breed them, but I believe GM stated that you should breed Lavender to Partridge to come up with the ideal "blue"....
