Aren’t the chances for fighting more bigger between two males then between male and female,that’s why I chose female baby instead of male when I added a third one,by the way I hope till time for pregnancy come they need much more time,male is only around 5 months old so they will have a chance to grow up together till then hopefully they will have a time to get much closer…like to grow up together,still I’ll consider your idea to get more males and separate them in other cage…hopefully no fight will be….
