Thats a good point. Or several. That's what I want to know, if what is happening to the little backyard quys. If you look at the chart, and figure there are thousands of backyard flocks, really very few of record are being affected. I read and heard that they compost the birds that they cull. I don't know if they compost the infected birds too, but really...compost? Back into the loop the virus goes....you would think, anyway.
