Hi, I'm a noob, to chickens and this forum. I'm hoping that a) I do this photo thing right; and b) someone can point out what the difference is with this supposed partridge rooster. Genetically speaking what is he, and what would he produce? I see this reference to calico and tortoiseshell, but if it isn't an actual color, this guy has an image issue (actually there are two with the same silvering along with the regular red partridge). Thanks for any input!
