I just candled the six eggs my silkie hen has been sitting on since Dec 2nd in the morning (so day 8). What should I be looking for, exactly, at this stage? I've looked over all the info & photos I could find but am stumped... These are brown/beige sexlink eggs. Four are really heavy and the light wouldn't pass through them, only appeared paler at one end of the egg. It's like a dark mass is stopping the light? But I don't see any "veining" or "the dark eye spot" anywhere For the last two eggs, the light passed right through them, I think they are infertile as I think I could see a yolk shadow in the middle of the eggs, not sure. These were very different from the other four. None of the eggs smell bad. Do we have chicks on the way???
