Honestly the best thing is for you to read through the course. The set up of the cage is not correct for your cham. They are arboreal so they need to climb and move around. Vines, branches, and plants should sit high up into the enclosure. Depending on what UVB lighting your using your distance to the closest branch is based on that specific info. For the correct UVB level at the branch. Without the correct set up and UVB exposure levels the cham can develop MBD.
It also looks like the feeder devise your using has food or something in it? Nothing but the bugs you feed that day should go into the feeder cup. Otherwise baby could very easily ingest the substance as well.
Your fogger should not run during the day at all. Only at night when temps are well below 67. If you can not achieve the temp drop needed then you would not use the fogger at all.
If you want to do a husbandry review we can go over additional info as well. Let me know and I will post the form for you to fill out.
