Just finishing my slide in hatching trays for my recently built incubator. Used 
Lexan for the fronts and backs so I and grand kids can watch the hatching process. Built (4) trays. The top tray has an extra piece of Lexan across the top and front ( This will keep the chicks from jumping out of the top hatching tray) because these trays are a bit longer than my Humidity pan shelf. Only did this to very top Hatching tray because all other trays below will have a tray above them so no little chick can hop out.
