So this is my first time incubating eggs and I am using a homemade incubator that so far works very well for me. I started off with 6 eggs from hens that family out of town owns. 2 of them turned out to be infertile. The 4 other eggs I candled a week or two ago and saw blood veins and signs of life. I candled them again a week later and it was still the same, but this week one of the eggs you could not see through it and it smelled bad so I tossed it. And again I have another one that I can't see any signs of life and it smells. But it's not all dark inside, I still think I see something(maybe). It also seems to be oozing brown stuff that smells. Before I toss this one I want to be sure that it is dead first, I would hate to toss a egg that still could hatch. I still have a feeling that it is dead. Please help! Thank you.
