Thanks, I have noticed that when I turn manually, some of the eggs do seem to be getting caught and not turning correctly. Maybe I should try taking some out. I don't think my chickens' eggs are terribly large or anything, but maybe it can't handle 18 of them.
I'm certain I have it set up right, and yeah, the small ends are pointed toward the center. It was turning without the eggs, so maybe fewer would work. I think for this run, I'll be turning them myself, but maybe next time I'll try fewer eggs. If that doesn't work, I have to think there might be something wrong with the motor on the egg turner assembly. I did buy it second hand. The owner said it had only been used once, but maybe the motor was damaged.
