I am new to this and have just candled for the first time. 8 eggs on day 10 and I might as well be looking at a test pattern on the T.V. I see some shadows, I think, in most of the eggs. But one shows what the pictures refer to as a blood ring. It is a definite black ring around the center of the egg. Should I throw it out, will it go nuclear on me if I leave it in there? Buff Orp eggs not too dark from my own young hens and rooster. Using a Streamlight XP and a paper cup with masking tape to focus the beam. I never did see anything that looked like veining in any of the eggs. Most appeared to have a black area and I could see the air pocket at the large end of the eggs. Not much else. Whatdaya think?
