I have a super broody, experienced mother, French Black Copper Marans broodie named Bessie. Today (2 1/2 days in) I noticed she abandoned one of her 14 eggs but was dutifully sitting the others. It also had some yolk on it so will check when I go back to see if another egg broke and leaked on it. When I candled and then cracked it I found it was not fertile. Has anyone else had a seasoned "pro" do this either because an egg became soiled or because they could somehow tell this early the egg was not fertile?
