A single Compy is never an issue. Due to there curious nature of humans they'll walk right up to you and observe you without hostility. But after they see you they will send out a call to nearby Campus beckoning them. Once another Compy is close enough to get a pack bonus they loose there neutral mentality and the pack mind takes over and they become hostile to beware of multiple Compys.
