Oh I see visible milkbands, always a good thing! LOL Congrats on the litter, hope she does well with it.

I'm the opposite about finding preggie rodents in pet shops. I've never seen a big benefit to it as you often get females so underfed and stressed from overcrowded housing that they drop poor litters or don't do as well as they should. I tend to get younger females and let them grow up with me for a month or so then breed them to one of my own colony males or just avoid the whole thing and breed my own next gen momma's.
