Beardies are solitary animals in the wild, they never "group together" in the wild at all. The parents come together to mate and then right after they mate they separate. The mother will lay the eggs and she's gone. The babies hatch and all separate immediately. They live completely alone 100% of the time except while mating. The reason that hatchlings and babies in pet stores and at breeders often have tail nips and missing toes is because they start being aggressive right after hatching, competing for food, basking spots, and everything else right away. Probably 95% or more of people who attempt to keep 2 beardies together that they buy at the same time when they're both very young babies, regardless of their sexes, end up with one beardie that is healthy, normal size, and thriving, and the other is stunted, emaciated, lethargic, and sick. That's because they determine which is the dominant and which is the submissive from the moment they see each other, and the submissive one always ends up becoming extremely sick, stunted, has deficiencies and diseases like MBD, and ends up dying before they hit a year old if the owner doesn't separate them and then get them medical care. And bringing 2 adult beardies together will end up the same way, the only difference is that the submissive dragon usually dies much more quickly due to a bite to the head, or worse, the owner comes home and finds one of their dragons missing feet, legs, their tail, etc. but still living... It's awful...So please, don't ever attempt to let 2 bearded dragons together, the best way to keep multiple beardies is to stack their enclosures on top of each other on a shelving unit so that they can't ever see each other, and let them each have separate out of enclosure times. Even when supervised they often attack each other too quickly for you to do anything about it. They don't want to be together, seeing each other stresses them out, and the only time they should ever even know that they both exist is if you want to allow a male and female to mate in quick, supervised sessions.
