Been years since I have candled at day 18. Can't find any good pics of candled eggs on the net @ day 18. All of the eggs are dark in the middle, air cells look good. But they all have clear spaces at the pointed end of the eggs. As I turn the eggs, I can see veining drooping down into the "clear area". I know that at this point the chick still has a certain amt of of yolk to absorb. But, can anyone help me and relieve my mind? Any help is greatly appreciated! Thanks in advance! Rand
