I believe they will produce follicles every year whether they have been paired off or not. So if she is wrapping does not necessarily mean she will lay eggs she may just be going through the process and will reabsorb the eggs later.

As far as her weight, I would really like to see a study where someone actually tags 50-100 1000g females in the wild with a GPS tracker then goes and studies them throughout breeding season to see how many are gravid, how many pass away from egg binding, etc.

In captivity we control what occurs and when, who controls it in the wild??

Just a thought don't mean to hi-jack the thread.
