I had my incubator boxed up and put away and I don't know what happened but I got it back out again!! I put two dozen of my eggs in it and after candling on day 10 I tossed eleven eggs as being not fertile or blood rings. Yesterday, out of the thirteen left, four hatched Now I know why I drug out my incubator again They seem to be all blue chicks with buff faces. My main roo is blue and most of my hens are buff but do have a few b/b/s in the flock of orpingtons. I do have a couple buff roos so who knows what the combination was? I see one more pipping now. Two have dark orangy faces and two have light faces, it will be interesting to see them feathered out.
