Is Random.Range in this script causing performance issues?

Hi, I'm definitely new to this and feel like I must be causing a dramatic frame rate drop with the following script:

 using UnityEngine;
 using System.Collections;
 
 public class Enemy1Controller : MonoBehaviour
 {
 
     GameObject player;
     public static float speed = 0.07f;
     Vector3 playerPosition;
     bool waitForCrowd;
     float waitTimer;
     float waitForCrowdCoolDown;
     public CircleCollider2D enemyProximityTrigger;
 
     void Start()
     {
         waitForCrowd = false;
         waitForCrowdCoolDown = 3;
         waitTimer = 0.5f;
         player = GameObject.Find("Player");
     }
 
     void Update()
     {
         CrowdCoolDown();
         Movement();
     }
 
     public void Movement()
     {
         if (waitForCrowd)
         {
             FightCrowd();
         }
         else
         {
             //Follows player
             playerPosition = player.transform.position;
             transform.position = Vector3.MoveTowards(transform.position, playerPosition, speed);
         }
     }
 
     public void FightCrowd()
     {
         //Pauses after trigger and cool down then bounces in a random direction
         waitTimer -= Time.deltaTime;
         if (waitTimer < 0)
         {
             int setRandDir = (int)Random.Range(0, 3);
             switch (setRandDir)
             {
                 case 0:
                     transform.Translate(0.2f, 0.0f, 0.0f);
                     Debug.Log("Left");
                     break;
                 case 1:
                     transform.Translate(0.0f, 0.2f, 0.0f);
                     Debug.Log("Up");
                     break;
                 case 2:
                     transform.Translate(-0.2f, 0.0f, 0.0f);
                     Debug.Log("Right");
                     break;
                 case 3:
                     transform.Translate(0.0f, -0.2f, 0.0f);
                     Debug.Log("Down");
                     break;
             }
             waitTimer = 0.5f;
             waitForCrowdCoolDown = 3;
             waitForCrowd = false;
         }
     }
 
     public void CrowdCoolDown()
     {
         waitForCrowdCoolDown -= Time.deltaTime;
         Debug.Log(waitForCrowdCoolDown);
     }
 
     void OnTriggerStay2D(Collider2D other)
     {
         Debug.Log("Triggered");
 
         if (waitForCrowdCoolDown <= 0)
         {
             //Reduces frequency of crowd interaction and not all react at the same time
             if (Random.Range(1f, 10f) < 2)  //Are too many of these at once to much to process?
                 waitForCrowd = true;
         }
         Debug.Log(waitForCrowd);
     }
 }

What happens here is many these "Enemy1" prefabs are Instatiated by a timer in another script. When they collide with each other while chasing the player, they have a chance of pausing for a moment and getting bumped around. When too many collisions are happening at once, the frame rate can plummet to single digits.

It is just a bunch of circle sprites chasing a square. It seems like when 4 to 6 of the circles are touching each other, that's when the frame rate drops to unbearable levels.

I was thinking the culprit might be the RNG being called so often but if anyone can point me in a better direct to get these results I would really appreciate it.
