Will, I wasn't upset that you answered the questions....I felt that it needed to be dealt with quickly too! The thanks was sincere!
I would still try the laying chamber as Will suggested, but I have a feeling that nothing will happen. If so, I would also recommend a visit to the vets (tell the vet as much as possible) again. S/he should be able to determine the size of the eggs and possibly see any problem from an x-ray.
Will said..."I have been told to administer 0.3 CCs of liquid calcium to females that are having difficulties laying, as it will A) replenish the calcium, B) Relax the muscles and help ease labour"...this is something I had discovered over 10 years ago...and it can help if there is no physical reason for her not laying the eggs. (Out of curiosity, Will, where did you learn this?)
Willl said..."I understand that Vets often prescribe a drug/hormone called oxytocin but that this drug might also lead way to other very serious health problems"...I don't know that it leads to health problems, but it will only work within a couple of days of the time that the chameleon should be laying the eggs anyway from what I've heard....and if the chameleon has a physical reason for not laying the eggs, it can cause problems. Oxytocin doesn't always work with chameleons anyhow...but there is another (more expensive) hormone (that I can't think of the name of at the moment) that works better.
There have been cases where the female reabsorbs the eggs....but these have not been scientifically documented. There is no proof that there is a "mechanism" that would allow it to happen.
