I have 4 eggs from JMajors. I am not sure what I should be seeing. They have been incubated for 10 days. One looks like it might have a blood ring, which now looks like it is fading. Another has one very red line in it, which wasn't there two days ago when I candled. Another looks clear, but the yolk part is pretty dark, and takes up half the egg. There are no visible veins in this one. The other also looks clear, but the yolk area doesn't take up as much of the egg? Any ideas? I also have 5 pekin duck eggs that were set at the same time, and there are 3 that have definite embryos in them. These eggs are from a chinese goose and pilgrim gander, if that makes a difference. Thanks!
