Your chameleon definitely has MBD...indicated by the deformed arms and the lack of trunkal lifting....don't know if she is impacted or constipated since I'm not a vet. Constipation often goes along with MBD though.
How many crickets/insects do you feed her in a week?
You need to get the MBD under control and then make sure your husbandry is right to keep it from coming back. The quickest way to correct the calcium imbalance is for the vet to give her injections of calcium and when her blood calcium levels are high enough, a shot of calcitonin, which rapidly draws the calcium back into her bones.
You said..."I picked up a liquid calcium stuff at the store, its' for people, can I give this to her?"...if its pure calcium sandoz or calcium gluconate or something similar, it should be fine. (no D3, etc. in it.) When giving it to her be careful that she doesn't aspirate it because those liquid calciums are usually syrupy and hard for the chameleon to swallow. I would ease it in a little at a time and give her time to deal with it before you give her a bit more. If you can get her to drink from a dripper, as her mouth is opening and shutting while she drinks you can slip a little liquid calcium in as she drinks. Since she has MBD its important to handle her with care because her jaw bones and legs, etc. are all delicate due to the lack of bone strength.
You should allow normal eating schedule IMHO.
I don't think she's old enough to produce eggs yet...I could be wrong but she doesn't seem to be showing the mustardy/yellowish splotches that a sexually mature female should show. However, its important to have an opaque container at least 12" deep x'12" x 8" filled with washed playsand in her cage once she is sexually mature so that you won't miss the subtle indications that she needs to lay eggs.
Should we use the "night" light that's like a black light until the new light gets here...does it produce UVB?
Your supplementing and gutloading/feeding of the insects need to be improved.
Here's some information I hope will help you with things like supplements, gutloading, etc....
Appropriate cage temperatures aid in digestion and thus play a part indirectly in nutrient absorption.
Exposure to UVB from either direct sunlight or a proper UVB light allows the chameleon to produce D3 so that it can use the calcium in its system to make/keep the bones strong and be used in other systems in the chameleon as well. The UVB should not pass through glass or plastic no matter whether its from the sun or the UVB light. The most often recommended UVB light is the long linear fluorescent Repti-sun 5.0 tube light. Some of the compacts, spirals and tube lights have caused health issues, but so far there have been no bad reports against this one.
Since many of the feeder insects we use in captivity have a poor ratio of calcium to phosphorus in them, its important to dust the insects just before you feed them to the chameleon at most feedings with a phos.-free calcium powder to help make up for it. (
I use Rep-cal phosphorus-free calcium).
If you also dust twice a month with a phos.-free calcium/D3 powder it will ensure that your chameleon gets some D3 without overdoing it. It leaves the chameleon to produce the rest of what it needs through its exposure to the UVB light. D3 from supplements can build up in the system but D3 produced from exposure to UVB shouldn't as long as the chameleon can move in and out of it. (
I use Rep-cal phos.-free calcium/D3).
Dusting twice a month as well with a vitamin powder that contains a beta carotene (prOformed) source of vitamin A will ensure that the chameleon gets some vitamins without the danger of overdosing the vitamin A. PrEformed sources of vitamin A can build up in the system and may prevent the D3 from doing its job and push the chameleon towards MBD. However, there is controversy as to whether all/any chameleons can convert the beta carotene and so some people give some prEformed vitamin A once in a while. (
I use herptivite which has beta carotene.)
Gutloading/feeding the insects well helps to provide what the chameleon needs. I gutload crickets, roaches, locusts, superworms, etc. with an assortment of greens (dandelions, kale, collards, endive, escarole, mustard greens, etc.) and veggies (carrots, squash, sweet potato, sweet red pepper, zucchini, etc.)
Calcium, phos., D3 and vitamin A are important players in bone health and other systems in the chameleon (muscles, etc.) and they need to be in balance. When trying to balance them, you need to look at the supplements, what you feed the insects and what you feed the chameleon.
Please note that various supplements have various amounts of D3 and vitamin A and so some can be given more often than others. The idea still is not to overdo the fat soluble vitamins like D3 and prEformed vitamin A.
