First season breeding and very excited!

But I'm wondering how much handling is acceptable post-ovulation? It has been a few days and my big girl is no longer swollen but I don't want to cause any unnecessary stress. Would it be best to confine her to her tub for the next month or so, or can I have her out for short periods of time?

I am also wondering if females tend to get more nippy/aggressive during this time? She struck at me for the first time while tending to her cage the other day - nothing serious, seemed to be a warning as she let me weigh her shortly after without fuss.

Thanks!
