Well I'm a little confused. Ok so last Wednesday I set 6 of my own ayam cemani and sulmtaler then bought in different lines to hatch so they're unrelated to mine so yes added more, ayam cemani eggs 6 sulmtaler eggs, both of which were shipped. So candled them. Sulmtaler shipped eggs are totally clear... But the shipped ayam cemani eggs which were all put in at same time have different stages of development :/ In 2 of them the embryos are moving about (little black dot) as we all know. Next 3 have veins and look like 2 days or 3 days younger than the other two I've the 48 auto incubator and I'd thought maybe the embryo ones where closer to the heat/fan...? But the larger two was beside at least one other egg same row so how the hell is there such a big difference?? Any insight folks..
