Roborovski hamsters do bite each other esp. at the backsides when they are older and get into contact with each other. My earliest case of backside biting was at 2 months of age. See another video. Bitten skin area leads to infection, hair loss from hamster licking and pain. Consult your vet early. 

This 18-month-old Roborovski was suspected to have backside lumps or abscess by this lady owner who keeps only Roborovskis as pets. This hamster had a bald backside area and so the 2 testicles were prominent. They were normal. No abscess as seen clearly under anaesthesia.  

Later the lady said that 2 months ago, this hamster was bitten by the other during changing of litter and there was some backside infection of the skin. Hence the scabs and hair loss.

Good news. Goes home after clipping and washing.
