I am considering setting up an enclosed trailer with 4 XL eggs inside. I would like them to remain inside at all times if possible. Any ideas on venting, I know I have seen the pics posted of an enlcosed trailer with 3-4 larges, looked like they had giant windows cut out but no exhaust hoods. I was wondering if that was enough ventilation. I am looking to primarily set up at local events and festivals throughout the year. Any advice or thouhts, feel free to chime in I am still obviously in the early stages of planning and any kinks that can be worked out or avoided based on this communities vast knowledge would be greatly appreciated.
