How many people use the sportsman for pea eggs? More importantly, which trays do you use? Do you stand the eggs up on ends to hold 20? Or use the tray that holds them on their sides to hold 12-15? I hand turned last year and had great success but it was hard on us to be here to babysit them. Looking to make it a bit easier on my wife and I, but do not want to ruin our hatch rates. Any info would be greatly appreciated.
