I am starting an orange headed roach colony for feeders for my roomate's and my panther chameleons. I have obtained an old chest freezer to locate them in the garage (no space in apartment). I got a freezer for the insulation since the garage is unheated and it gets ultra cold here, I will be using a ceramic heater to heat them. My biggest concern is airflow. Does anybody have any ideas on keeping them well aired out, other than opening the top frequently?
Thanks
