A lot of people who receive their first jumbo quail eggs (especially JMF eggs) have issues fitting them into the rails on little giant or gqf automatic turners. 13-15 gram eggs can't be fit into both rows on one quail egg tray either because of their girth or height. They will either be too wide to even fit side by side, or the edge of the next tray will break the eggs. The best way I've found so far and lose no eggs is to use the outer rows on 4 quail rails and use one chicken rail between two of the quail rails. This allows you to fit 47 eggs in one turner without risking damage to any of them.
