After candling my eggs for day 6, I decided for learnings sake, to break open the ones that didnt appear to have developed. They all had no signs of veining at all, and their yolks were VERY fragile, and the white very watery. One egg was actually scrambled on the inside. Of the 18 eggs that were sent from across the state ( so not far) only 9 show veining at 6 days. they others were as above. Is all of this normal? This is my first batch so I am just trying to learn. It seems a very low development rate. Oh, one egg was broken when i got the eggs, so 9 veined and 8 are duds. So is this normal?
