I'm new to hatching. But I cannot find any picture anywhere that matches what I've seen. Ill try to explain. I candled at day 4 and it looked like 2 out of 8 eggs were fertile. Now on day 7 the two that were fertile look different. I see the eye inside but the veins and chick are on one side. Not top or bottom but one side of the egg. In other words look at an egg and draw a line down the center the LONG way. Both chicks are on one side and one side looks clear. Is this normal? They we in my brinsea mini advance being turned regularly so I thought everything was fine. Advice?
