Collision not getting detected between 2 colliders

So I have a navmesh agent I used on a chicken model to get it to run away from a mouseclick, but for some reason, its collider does not detect any collision with any other colliders. I've tried using OnCollisionEnter as well as OnTriggerEnter, but still nothing. Here's my syntax:

 public LayerMask clickOn;
 private NavMeshAgent myAgent;
 RaycastHit hitInfo;
 public float fleeDistance;

 void Start()
 {
     myAgent = GetComponent<NavMeshAgent>();
 }
 void Update()
 {
     if (Input.GetMouseButton(0))
     {
         Ray myRay = Camera.main.ScreenPointToRay(Input.mousePosition);
         if(Physics.Raycast(myRay, out hitInfo, 100, clickOn))
         {
             runFrom();
         }
     }
 }
 private void runFrom()
 {
     float distance = Vector3.Distance(transform.position, hitInfo.point);
     if(distance < fleeDistance)
     {
         Vector3 dirToClick = transform.position - hitInfo.point;
         Vector3 newPos = transform.position + dirToClick;
         myAgent.SetDestination(newPos);
     }
 }
  void OnCollisionEnter(Collision collision)
 {
     Debug.Log("hit");
     Destroy(gameObject);
 }
