I have even tracked down a dozen mutt eggs from the neighbor. Hers aren't laying very well and they are eating all the eggs with no extras but, I made a deal. One dozen of my girls egg's for one dozen of their girl's eggs!
I'm thinking about what I might get if I cross my "mutt" with my RIR (if they are a hen and roo) I'd like to see if his "head fan" would carry through but with on a bird with more red instead of "dirty" looking.
