Hi everyone I am new I have a few questions to ask. Ok so let me get started:: I am incubating my duck eggs, this morning I went out to collect and I candle it with flashlight one has a tiny blood spot inside that's not near the yolk and on the outside of the egg where the blood spot is there is a circle engraved around the blood spot. My question is can I still incubate the egg and it be fertile. I don't want to put a bad egg in with the others. I'm in closing a photo of egg. Thanks for your help.
