I found I able to look at the eggs wit h something with a glass door most the time with out opening the door. to see if they too dry or humid. But I got an old cola machine for 100 bucks and redone it . I can hold possible 8-10 clutches depending on their size. the cooler works to as you don't have to it taking up space all year around. I reuse my cola machine to store extra tubs and other reptile items during he off season when not being used
