Hi, this is my first attempt to hatch, and am using a brinsea octogon 40 dx incubator. I started with 6 black copper marans, 6 blue ameracaunas, and 8 welsummers (all shipped, I ordered 6 welsummers, but she sent me 8) anyway, I am down to 5 welsummers due to weeping eggs. I smell a kind of "bad" smell from the bator, and have smelled the eggs. 2 more welsummers are "iffy" They have an odor, which MAY be rotten, but not sure. I tried to candle them ,using a small flashlight, (that's all we have) but don't know what I am supposed to see. I see a blob with space at the end. If they have a slight smell, are they rotten then? Can someone tell me if I should throw them out, or wait? Also, should I just give up trying to candle? I don't know what I am supposed to be seeing. It's day 13 today. Thank you!
