So I have owned dubia roaches for over 2 weeks.. the room they are in stays between 70 to 75 and they always have the dry dubia diet and water crystals.. I also give them grapes or oranges as fruits and they are in a huge plastic tote with large air vents cut into the lid with aluminum screen hot glued over the holes and plenty of egg crates.. but in the past few days I've had about 10 die on me.. not a single big one only small ones under an inch.. is this normal? there is roughly 250 dubias in the cage but shockingly it's not crowded.. a lot of the egg crates are less than 1/4th full so I dunno.. could it be humidity related? I mist my t's enclosure but never mist the dubias
