Question Stop gameObject from pushing itself using isKinematic

Hey everyone!

How can I stop a gameobject from pushing a clone of itself around? I have a chicken that's being duplicated around the scene many times. They are all the same gameobject with a box collider, a rigidbody and the script you see bellow (Eventually I will convert to prefab).

The game itself is simple...some of the chickens can only move horizontally, others only vertically based on the "swipe" direction...which I'm testing now with mouseDown and mouseUp.

I have tried the following, but i'm stuck:

- On start I set the chicken's rigidbody to isKinematic
- Then when I click the mouse on it, I set isKinematic to false (so it can move)
- Then onCollisionEnter if I hit the "Chicken", I set isKinematic to true (so it can't be pushed anymore)
- Now when I click again on it, (it should set the isKinematic to false, so it can move again) but it's stuck and can't figure out how to reset the isKinematic again...

I would appreciate your help! Thank you!
