This is my first time hatching eggs, and it seems that no matter how much I research I do I end up with more new questions than answers. I originally had quite a few duck eggs in a homemade incubator. After clearing out the ones with nothing in them I found a few that scrambled and 1 that had a for sure blood ring. I have 9 left and today is day 8. last night I noticed all my eggs had rings. My inner dialogue when something like this "How could they have all gone bad? Maybe it's not a blood ring maybe it's something else and it's normal. " so I drew a line around the ring and figured if it grew by the time I candled again that it was a normal thing. and I had not planned to candle again until day 14 but something told me to this morning so I did. however what I have found is that all of the babies have moved along with the ring. they are not floating around in there and they don't move as I turn the egg but they have all rose to the top of the egg over the course of a few hours. is that normal? so this is the ring I'm talking about. Is that a blood ring or something else. and this one shows how much it moved last night. you can see my pencil mark and then the ring in question. (btw the embryo in this looks like the other one it's just on the very top of the egg almost on the other side.) If anyone can help me with this I would gladly appreciate it.
