I'm heartbroken. Out of 36 eggs, only 1 is still alive. It's on day 13, and wobbled on the float test, and I can feel it moving in the egg when I held it in my hand. So it's sitting there in the incubator alone now. Temp is 100.5 and humidity is 67% right now and holding pretty steady. Do I need to do anything else? Most the shell? Put it under a light? Is there ANYTHING I can do to help give it a fighting chance?
