Today is day 10, and I have attempted to candle some eggs. The very dark eggs, Welsummers and Wheaton Marans, I cannot see at all except possibly the air cell. Some of the orps I can see darkness below the cell, but really can't identify veining. In some of the ducks, I think I see an ugly blood blob, and one definately had a blood ring. So my mag lite is too weak evidently even though I locked myself in a dark closet. My eggs are getting cold while I try to decide what I'm seeing. What's the harm of just not candling? Can I just "follow my nose" and sniff out a bad egg instead of candling? It seems like such a guessing game and I feel frustrated with it.
