So my black berkshire ratty might be pregnant. I just got her, and she is still young, so she may be pregnant with her first litter as I picked her up from another breeder. Not the best practices, but the ratty is healthy and looks great so I'm pretty happy.

Anyway, she is only 8 oz right now. I know a good way to track pregnancy is by weight. If she steadily gains weight, I'm guessing she is, but we will have to see.

Behavior wise, she doesn't seem interested in the male and vise versa. She has been friendly. She feels a little fat to the belly, a little bit firm but not overly so. She is in the corner and has made a nice simple nest, that only has shallow sides. Something that I think a non-pregnant rat would make, but again I'm a novice!!!

Now, my other female is a bit smaller than the berkshire, and she was actively teasing the male. They slept together a few nights. Now that the new female is here, they are often in their own corner but no fighting at all. I check on them very often as I have been on vacation.

Anyway, I would love thoughts and comments.

Besides the fact that they are still pretty young, but it's better to breed them at this size than at 6 weeks old that's for sure!
