Please watch the video about egg laying below. It shows examples of what a receptive and gravid chameleon look like.
Here is some feedback/suggestions:
1. Superworms are not very nutritional and should only be fed as treats. Please try to diversify her bugs to include things like crickets, dubia roaches, silkworms, BSFL, etc.
2. Does your multivitamin have D3 in it?
3. How often are you misting?
4. Lower her temps to 80F. Higher temps = more eggs.
5. Since you have a 4ft tall enclosure, you'll want to switch to a 5.0 T5 HO UVB
6. Humidity is on the high side. Should be closer to 30-40%
7. I would add in WAY more branches and plants. Any empty space is unused space.
