After making an incubator and not having any patience for my pheasants to lay, I got 4 duck eggs from a friend, and put them in the bator. I candled today, and I have one with spider legs, 2 with some kind of dark mass, and one clear. The clear was removed, and now I don't know what to do with the other two. I will wait, and candle again to see if anything's going on. Is this dark mass normal, or is it the yoke? This is my first time at incubating anything, and only know what I read here. Thanks
