Ok, I couldn't help myself and wanted to check to see if I have any veins. I'm 4 days in, and the only thing I see is the dark circle at the large end of the egg... I do not see a yolk just clear (or so it would seem). I do have some brown eggs and green (my mutt eggs). So I'm not exactly sure what to make of this... I should mention this is my first attempt at incubating, and I'm a bit nervous... If I did hard boil them in the bator how would I tell?
