baby hamster fighting

Question
my hamster had babies ...she did not eat any of them and she takes good care of them ...they are a little bit over 2 weeks old and almost evey night i hear them fighting and making noises ...i dont no if it is play fighting or real fighting.....do i separate them from each other...i am very worries that they might kill each other

Answer
At this age the baby hamsters are just playing around.  It is not until they reach weaning age of three weeks that I'd show any concern over this.  When they do reach nearly four weeks, try to separate them by gender in two other enclosures.  One for boys, one for girls.  Not in the same place as their mother.  Once they reach the age of 5 weeks they are sexually mature and can breed.  Make sure there is plenty of food in each cage so they wont fight over food.
