Apparently the one egg I've had trouble candling is a black copper maran egg. I was gonna toss it, but now that I've read up on how hard they can be to candle, I'm hesitating. All I can see is the air space and a faint dark blob that moves slowly when the egg is turned... no movement, no obvious veins, no details of any sort- just a fuzzy dark blob. Is that normal? My gut is telling me "keep it" but lockdown is on Thursday and, while its not smelly now, I'm worried about it being a "bad egg" and potentially ruining the rest of the hatch.
