Ok with the feeders... They are a bit too large for the size of the chameleon. I would not feed any larger than 1/2 inch in length for crickets. and the cham should be eating much more like up to 2 dozen a day.
- Feeding - He eats crickets and sometimes i give him roaches. Around 3-6 crickets with calcium every morning. Gut load mostly with bee pollen, lettuce and other greens.
- Supplements - Calcium every day with his food. D3 and vitamins every two weeks.
Your supplements though need a correction. your multivitamin already has D3 in it. So you want to stop using the calcium with D3. You will use the plain calcium without D3 at all feedings lightly dusted on the insects prior to feeding. Then two times a month you will use the Multivitamin on say the 1st and the 15th. This will cover all supplementation.
You can fog at night you just want to make sure your temps are lower so under 68F. you can also mist the enclosure and all the plants. Just do not spray the cham directly or the shed will stick to the skin and not come off easily.Humidity - Humidity around 40%. It´s the humidity I have in my room. At night it should go higher but I´m scared to do that at the moment because of his shed.
I do not see anything else off in your husbandry. Put a solid divider between the two cages so the cham can not see whatever is in the cage next to it.
I still think the cham got wet just prior to shed and this is why it is coming off in tiny pieces.
