I candled tonight, because I'm impatient like that. I pulled 11 eggs from the bator. 9 of my cochin eggs were infertile. Oddly enough I have 2 girls in the pen, they lay different colored eggs. One darker than the other. One girl is clearly fertile and the other is not. Clearly my frizzle cochin roo Elvis is not spreading the love! I also pulled 2 buff laced polish eggs. But my Ameraucanas and WCB Polish are developing at 100%!
