Hello my name is angie, I'm new a all this incubation and hatching an egg information. So i've been incubating a duck egg for 22 days now and it looks fuller and seems to be heavier than before. Although thats the case, I am not sure if its alive or not, it has this new blue spot on the top of the tip of the egg, on the opposite side of the air sack, and has started to turn like a lightish blue color around the blue dot. Im worried I wanna know if it died or is still alive. can someone help? I've got a few pictures I'm going to post to see if it helps you guys tell and help me out!
