This is my third breeding season. I did not take note in previous years, but I just noticed something...

I have several girls that I know are gravid, and within days of laying...

These girls, of course, have not eaten 6 or more weeks.

I just noticed, that several of these gravid girls have just urinated and/or defecated a little bit, when they have not done so for some time. Is this a common sign that they are about to lay?
