I set 12 guinea egg last friday night. I tried candling them this morning and I am not sure exactly what I am looking for. These eggs were shipped and they are a lightish brown/tan color, some are speckled, so it is hard to see. Some of the air sacs in the eggs seem to float or move toward whatever side of the egg is up... the others seem to stay stationary in the large end of the egg... which is how I thought they were supposed to stay. What does that mean? In a few of them I can see the veins. Some appear to have just a small dark spot, but I can't really see any veins, is it still too early to tell? Thank You!
