I know it is probably an old topic here. I have read most of the posts on the threads but I still have a questions. I have RIRs and I want to start selling eggs. I have bought a candle from a feed store but don't really see much. When you candle eggs are you looking for blood spots or are you looking for fertilized eggs, or are you looking for both? When I eat my eggs and simply remove any tiny blood spot with a spoon before cooking them. I don't have many eggs with spots but I still would feel funny if someone found some and was not happy?
Thank you
