Candling... early development... and new to incubating

[Mycookoonest]

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?

wait until day 8 you may see more. I don't always see viens just a dark area that gets bigger so if you don't see viens don't throw the eggs !
