Today was day 7 for incubating my Ancona duck eggs. I have 12 and 5 of them were clearly progressing. You could see the heart and all the veins forming. One was definitely infertile but the remaining 6 I’m not sure on. This is my first time doing this. I can see a black spot and a large dark area around them but no clear veins. I’ve left them in the incubator (marked with ?) and planned on giving them a few more days but figured I’d ask here and see if anyone knew.
