Well, I was told that they just started breeding a month ago, but now looking at the picture of the colony they sent me, it is not the one that they sold be.
She did end up dying, and she looked like she was due to have her babies any day, so that really ticks me off.
On top of her and my nursing rat, one of my babies also recently died. She was the runt though. She was also my favorite, and I had planned on retaining her. She was a one-eyed hairless.
