Thanks Becky. I'm just trying to figure out how this happened and how I missed it up until tonight when I seperated her out. Granted she was "just" a feeder and in a big female feeder bin which I do not handle the rats from. Worst part is I've no idea which male fathered her LOL. Obviously Patches must have carried the Dumbo gene but apparently one of my colony males does. Now I'll just have to figure out which one it is.
