I agree in that you should just try her out in an egg laying container, whether you put it in her cage or put her in another. Do it however it worked last time. I wouldn't be suprised if she was ready to lay (by the time frame you said) because some chameleons are quick in their turnaround. I don't suppose you weighed her before she laid last time did you? If you did (nobody seems to do that but it helps SO MUCH! COME ON PEOPLE!) she will be close to the same weight when she's ready to lay again. For example, a chameleon (veiled or whatever) weighs 85 grams when she's ready to lay. She lays her eggs and gets down to 60. The next time that she is ready to lay, she'll be close to 85 grams again or slightly more (because of growth). Once a female is bred, they don't grow a whole lot more after that (kinda stunts it). They get the sperm retention thing going and it takes all their body's strength to make the eggs. That's why you need to supplement gravid girls so much. Good luck with whatever happens.
