Hello, I had 5 chicks last summer so they are now around 8 months old. One of the hens has been sitting on her eggs for 12 days so I had a look with a light to see if anything inside. There's an air sac but no veining or sign of an eye, just a dark blob floating at the top. Why is there no chick?? I have 1 cockerel to 4 hens. I've believed the eggs to be fertile as I've seen the bullseye when I cook with them but am I wrong?? 1st time chicken keeper! Any help appreciated. Photo of an egg I collected today, is it fertile?
