Meh... you do communal breedig don't you? I have a VERY hard time believing one female gave you 32. I can see you have newborns in that pile, and a few a couple of days older that have developed their pattern. Sorry, that is two litters there.
Also... if you've been having problems just getting animals to not eat their young, how could you have been "working" on selectively breeding for larger litters over so many generations now? Things like that take time...
