LOL @Jessimom funny ovate!!
I candle and rotate eggs and rotate trays,
The trays always move up from bottom to top, top tray goes to lockdown because I stagger in the cabinet cooler.
I pull all the trays out candle rotate and put them back in and add new and move others to lockdown. color codes work quickly for me with as many staggereds as I do, and having so many coolers to work with helps tons too!!
