I dont see anything about white flecks in the breast being a defect. The standard simply says Breast: lustrous greenish black. I have seen many silver pencilled and partridge roosters that have some flecks in their breasts so I dont think it would be that much of a problem. I would send the one with the best type. If you go to acornhollows site they have the ideal wyandotte type in a figure drawing.
I know what you mean about the new standard, I remember every one was getting excited for the 2007 standard then they said 2008 now its 2009, its crazy. I am waiting anxiously for them to hurry up with it.
I saw your wyandottes on eggbid, they look pretty good and I was suprised to hear they are from a hatchery.
