I candled my ducks eggs, on day 5, I couldn't wait to take a peek... I only have 5 eggs in my bator, three look completely clear with nothing going on but I know it's early so I'll let them sit awhile still. One has clear normal looking veins in spider-webby patterns. The other one, I thought was veins, but I'm not sure. It really only was one vein, in a circle. Like a red line in an uneven ring. Again, it's early so I guess it could still be veining, but I wonder if it's a blood ring... I guess what I'm asking is; From the get go, do the developing veins spread out in the tree branch or webby pattern or do they start as one vein and grow from there?
