Hi Heather! Unfortunately, or fortunately, all of my buns are very different from each other... However out at the sanctuary we have a lot of twin, triples, quadruplets and a set of quintuplets. It gets really confusing when we do health checks to figure out which one we've got in our arms at the moment and who still needs their checkup. Many times it's just a matter of a small telltale sign but it still is a challenge.
