Another quick Dumbo question - sorry for the hijack Robin - but I can't seem to find a good answer on this issue. Is the genetics that create the lower set ears and the slightly different face of a Dumbo related to any genetic faults? In other words when choosing to create Dumbo eared rats am I risking in any way bringing a slightly less than good genetic line into my colony? I just want to make sure that what I do doesn't hurt the rats or if I need to be very careful in which male I breed Dee to as her next litter will start the steps to producing my own Dumbo's (this current litter of hers being all marked as feeders).
