Predicate for aggroed Zoglin

Hello, 
Been struggling with this for a few hours and decided it was time to ask for help. I've been trying to use Misode's predicate generator. 
I'm trying to use a predicate to detect if a Zoglin is hunting anything. It doesn't matter what its hunting from a rabbit, to a player, to a zombie. I just want to detect any time its hunting anything. 
At first, since zoglins sprints, I tried detecting its change of speed. 
{
    "condition": "entity_properties",
    "entity": "this",
    "predicate": {
        "type": "minecraft:zoglin",
        "movement": {
            "speed": {
                "max": 500,
                "min": 0.1
            }
        }
    }
}
This didn't work and would never count as true no matter how low I made the min speed. So it wasn't even detecting its base speed.
{
  "condition": "minecraft:entity_properties",
  "entity": "this",
  "predicate": {
    "type": "minecraft:zoglin",
    "targeted_entity": {
      "type": "minecraft:villager"
}

  }
}
Then I tried detecting when it was agroed onto things, in the above example I was trying to detect if it was aggroed on some poor villagers I was testing with. 
I am sure I have some simple issue or concept I am missing and would love someone to point me in the right direction.
