Poorly Veiled, Burns? Markings?

Hi guys,
I have recently been forced to working away and despite countless notes and "tutor lessons" i have come home to find Chamy a little under the weather.
Here's the notes and pics hoping one of you guys can possibly identify it before i get her to a vets next week.

Chameleon Info:
Your Chameleon - Veiled, female, 3 years old, had her from a hatchling
Handling - she isn't the friendly type so barely never!
Feeding - Main diet of silent brown crickets, around 7-9 large every other day (always crickets left) feeders are gut loaded on garden weeds and veg. weeds aren't sprayed)
Supplements - suspect i've been ill advised by only using calci-dust on every feed since owning her.
Watering - Auto misting system which soaks the viv 3 times a day for about 30-40 seconds. Very rarely see her drinking
Fecal Description - solid and white, few orange colours.
History - Suspect a huge overdose in calci powder, the feeding box was covered!

Cage Info:
Cage Type - wooden sides and back glass slide front, 100cm wide, 100cm tall 70cm deep
Lighting - All lucky reptile, can't remember what UV lamp is used but it is correct for chameleon, 100w day glo halogen
Temperature - basking spot is around 84-86, unsure on temperature away from there, much cooler obviously. lowest temp at night is 79-80, digital gauge and thermostat
Humidity - average humidity around 65-75% frequent misting and occasional fogger on dry days. stand alone humidity gauge
Plants - 6 live plants, all safe with chameleon
Placement - in my bedroom, remotely located air fans to vent viv (low noise and away from her) viv located on the floor.
Location - UK, south east

Weird markings on her head, apparently been like it for about 2 months and hasn't got much worse, she has stopped eating (bored of crickets i suspect!) and has shed her skin since it was noticed. Generally apart from being grumpy (as always) she seems happy enough, hiding and chilling as usual, having a wander about! bit of a wierd one! hope you guys can help though

Any ideas guys?

Hi there!

Yes sadly that looks like a burn to me. I think 100w is probably too hot for a female, her basking spot should be around 80f or 27c but your temps are not that far off. You need to make sure her basking spot is a good few inches under the light so she cant reach the really hot parts of the enclosure. I would take her to the vet and get that casque checked on if I were you.

Now the poop should be brown with a white part. If this white part is orange then that could be a sign of dehydration. Her eyes look a little sunken in which is also a sign of dehydration. You may want to up your misting and add a dripper.

For supplements you would want to use plain calcium at most feedings and you would also like to use calcium with d3 twice a mont and multivitamin twice a month. The d3 will help her process the plain calcium, otherwise there is a risk that it could build up in her system. The multivitamin does a lot of things for eyesight, skin health, tounge health etc.

You may want to try some different feeders such as horn worms, silk worms, locusts, roaches, butterworms just because a varied diet is really good for them.
you could afford to drop the night time temps a bit because they like it to be cool at bed time. This will promote a good sleep and helps thier system slow down foe sleep.

Has she ever laid eggs? I knoe this does not relate to your problem but i'd be interested to know

i hope this was helpful, please feel free to ask any more questions you may have !

Very very helpful thank you! :-D
I'll sort those point out asap, she is all booked in at a vets for a double check

She has indeed layed 3 batches of eggs (usually always after a deep clean so she can throw sand out everywhere and make a mess again naturally!!)

Hello, welcome to the forum I agree with everything AngieL says, also I think your gutloading could be a bit better. Apart from the burn she looks good though, so you must be doing well with her. Dropping temps a bit and food intake will help to limit the amount of eggs she cycles so will hopefully prolong her life. Here is a great all-round caresheet for Veileds - https://www.chameleonforums.com/blogs/chameleonsinmyhouse/395-veiled-chameleon-care-sheet.html
And some more gutloading info. - https://www.chameleonforums.com/blogs/sandrachameleon/75-feeder-nutrition-gutloading.html
You can also buy some pretty good commercial gutload products like Repashy bug burger (which is the one I use).

I'm glad I was of some help. This forum had taught me all I know and I'm so greatfull for that! Im happy you're taking her to the vet, you have to let us know how it goes cause I'm attached now

They like to try you don't they? My girl hasnt laid eggs yet but she likes to poop everywhere! Especially just after the plants have been washed
