How to move more than one object together at a time?

They suppose to move to a new position when hitting Z key but they all stuck together in a same position. Is there any way to solve this problem? Please help. Thanks in advance

 public void moveEgg()
    {
        if (Input.GetKeyDown(KeyCode.Z))
        {
            transform.position = Vector2.MoveTowards(eggPositionLeft, EggSpawn.eggPosition[5], 0 * Time.deltaTime);
            transform.position = Vector2.MoveTowards(EggSpawn.eggPosition[5], EggSpawn.eggPosition[4], 0 * Time.deltaTime);
            transform.position = Vector2.MoveTowards(EggSpawn.eggPosition[4], EggSpawn.eggPosition[3], 0 * Time.deltaTime);
            transform.position = Vector2.MoveTowards(EggSpawn.eggPosition[3], EggSpawn.eggPosition[2], 0 * Time.deltaTime);
            transform.position = Vector2.MoveTowards(EggSpawn.eggPosition[2], EggSpawn.eggPosition[1], 0 * Time.deltaTime);
        }
}

You are passing in zero as the amount to move to the MoveTowards function: 0 * Time.deltaTime. Pass in anything else, and they will move.
