I am new to breeding rats and so far things have been going great! I run 1.4 in each large tub and keep them together at all times. This last time I decided to move the female into her own tub instead of keeping her with the others. Two days ago she had her litter of 10 and everything looked fine. I would peak in on them throughout the day and noticed she wasn't paying any attention to them and it started to get me a little worried. Today I came down to check and all of the pinkies were dead and the mom was just going about her business as usual. The only thing I can think of is that I moved the mom and stressed her out with the move. I read as much as I can on this forum regarding rat breeding and see many different opinions on the topic of moving females/males; any opinions on this would be greatly appreciated.

Thanks,
Bill
