I bought six of these eggs. All were fertile and developed fully, five hatched. Two roos, three pullets. One laid very dark eggs, still does, one laid decent and one laid so light I gave her away. The roosters are very handsome, fertile, good sized, good dispositions. The one hen I let brood was an excellent brooder. I hatched a whole clutch of the first laid pullet eggs from my dark layer, and am waiting for them to start laying in a couple more months. you can see pix if you click on the Website link by my avatar.
