Is she still in the tiny enclosure? Is so, she may be going to the bottom to try and find more space. From the pics you posted I’m not seeing gravid coloring. Usually their colors and patterns are very pronounced and they darken. However, each chameleon is unique. I’m hoping she isn’t gravid and won’t be until she’s had at least a couple of months of proper care. With mbd, she may have difficulty laying and need veterinary help. Here’s my ‘laying 101’ ramble though.
I’ve already told you about setting up a good lay bin. You’ll want that to become a permanent part of her enclosure to avoid guessing when she needs it. Just before laying, her appetite may decrease, color becomes dark and she may become a bit restless, looking more to the bottom of the enclosure. She’ll find the bin when she needs it…or she may prefer to use a potted plant. Once she enters her bin and starts digging, she’ll need total privacy. It’s best to cover the visible part of the enclosure (usually just lower half) with a light sheet. You can make small holes to peek thru. It’s very important she doesn’t see anyone though or she may stop digging and could become eggbound. You don’t want to worry about feeding her, you can use your dripper or mister on it’s usual schedule and keep your lights on their usual schedule. At night, she may sleep in her tunnel. She may dig several holes until she’s happy with one. When she’s finished digging, she’ll turn around so her face is out of the tunnel and lay her eggs. When done, she’ll carefully and thoroughly cover all of her holes in and return to her basking branch, looking dirty and much thinner. The whole process may take 1-2 days. Once she’s back at her basking area, you’ll want to feed and hydrate her well for a couple of days. I love giving some hornworms and silkworms at this time for the hydration. When she’s settled and is back to her usual within a day or so, you’ll want to remove and count the eggs. Hopefully there will be only 20/less than 30. Since she’s never been mated the eggs are infertile and can be tossed out.
After a couple of days of feeding her well, you’ll want to start feeding her 3-4 feeders, 3 days a week and be diligent about her basking temp not going any higher than 80. We do this to try to reduce egg production and laying, both which are very hard on our ladies and shorten their lives greatly.
Signs that all is not going according to plan and she may need veterinary care - eyes closed during the day, lethargy, staying low in the enclosure all the time/not basking, not eating/drinking, not completing her laying (not covering her holes, still looking lumpy/plump, etc) and days later returning to dig again and anything else that you just feel doesn’t seem right. Always go with your gut feelings. It’s better to take an animal to the vet and have them find nothing than risk possible illness.
I think I’ve covered it all, but I’m not fully caffeinated yet and may have forgotten something.
