The best option and the fastest way to get the calcium issues under control would be to see a vet. The vet could give him calcium injections and when the blood calcium levels are high enough the chameleon could be given an injection of calcitonin to draw the calcium back into the bones. Even if the vets are not familiar with chameleons they could phone a vet who is to get directions.
I am not a vet and the following is only meant to help until you can see a vet. Some of it is meant to help while the chameleon is recovering too.
In the meantime, you could give is some liquid calcium sandoz or calcium gluconate. You can buy it at a pharmacy usually. If you can get it some direct sun that would help too. If its cool outside you could put a basking light over the chameleon but place it in direct sunlight at the same time...but I still wouldn't put it outside if its below 70F since its not well to begin with.
Baby food chicken has preformed vitamin A in it and that could fight against the D3 and thus keep the chameleon from recovering IMHO.
If it will take crickets on its own, that is what I would give it...making sure that they are well gutloaded. I would stay away from the mealworms because they are harder to digest and likely the chameleon's bowels won't be working really well due to the lack of food lately and the calcium issues.
Once the health issues have been addressed, you need to (of course) keep the chameleon properly to prevent it from happening again.
Exposure to UVB will allow the chameleon to produce D3 which will allow it to use the calcium.
Since many feeder insects have a poor ratio of calcium to phosphorous, dusting the insects (before you give them to the chameleon) with a phos.-free calcium powder at most feedings will help to make up for this.
I dust with vitamins with a beta carotene (prOformed) source of vitamin A twice a month since beta carotene won't build up in the system. Its not know if all/any chameleons can convert the beta carotene but doing it this way puts you in control of whether to give it prEformed vitamin A or not. Excess prEformed vitamin A can prevent the D3 from doing its job and push the chameleon towards MBD....so it should be given carefully.
I also dust with a phos.-free calcium/D3 powder twice a month. D3 from supplements can build up in the system though, so don't overdo it.
Phos., calcium, D3 and vitamin A are important players in bone health and in other systems in the body and need to be in balance.
Gutloading/feeding the insects a nutritious diet and providing appropriate temperatures is also important.

If the chameleon is brought back into good health, it might still live a long life...as long as the damage hasn't been too bad.
Good luck!
