Don't tip the eggs unless you want them to die. They need to be level and in a consistant environment, as they have an air bubble in the egg that if it moves or ruptures, will kill the embryo.
You need an incubator.
You can't incubate eggs just in an incubator alone. You need humidity and stable substrate as well, which is why we have this thread right here..... THEN you put it in the incubator...that is running at 89 degrees or so evenly.
