I can see lots of candling posts but wondered if someone would have a look at my duck egg and advise if it might have died please. I had movement in the egg last weekend but can't see any now, although the veins all look fine and I don't think I have a blood ring. Would really appreciate an opinion. Thank you. Also the incubator is a mini and doesn't show humidity, do I need to buy a humidity thermometer to put in the incubator? Many thanks x
