ok, today is day 6 of incubating. I have 36 eggs and they are a Buff orpintons,rose comb brown leghorns, Rhode island reds. I got a little impatient and candled 2 eggs from each breed and didn't see any of the veins or spots like all the pictures and videos show. I had one egg that was cracking so I took it out and opened the egg and you can tell the egg was fertile and their was some kind of developing but nothing that I would call good formation. and their were no blood veins in there. any ideas? when I got the eggs I had a few extras that I cracked and they have all been fertile.
