I was having a similar problem with the same LG incubator. I happened across a thread,maybe on here, talking about fresh air circulation. I then realized my plugs were in on the top of the LG. I took one out and my eggs started hatching. I went thru over 50 eggs before I got one to hatch. They always died in the shell.
