After I bought the egg turner, I only open my incubator twice a week to add water. Tonight I found the incubator was very stinky and had to check if any egg broken. I did find one broken egg, which had some yellow and black liquid leaking out. I have to take out all the eggs and clean the incubator very quickly. While after that, the incubator still smell not good. The broken egg was very smelly and made me sick. I am worried about the eggs in the incubator, as I know the smelly egg would send out H2S, which is poison. The birds were supposed to come out on this coming Thurday. I hope they would be ok.
