I don't have eggs to add to it yet, but am trying to get my 'ducks' in a row. There is a little (1/4"?) pie-shaped divider in there on top of the mesh. HOW do you make sure the eggs are fat side up? Do you lay the eggs on their sides with the fat side towards the middle of the 'bator? I can't see how you could 'stack' them so they would be little side straight down. I downloaded the instructions and cannot 'see' how it is done. I am borrowing this incubator and the owners said their last hatch was unsuccessful. I do not know how many hatches they have had. Thanks!
