Unpackage hens over the sink and pour juices down the drain. Pat dry inside and out with paper towels
In a small mixing bowl, add tarragon, garlic powder, onion powder, smoked paprika, salt and pepper. Mix together with a whisk until combined. You will have extra rub, so don't stress.
Preheat the air fryer to 400 degrees F and set the timer for 40 minutes.
Pour a small amount of olive oil on your hand and rub both the birds to coat the skin, front and back.
Hold one of the birds in one hand and scoop up some of the rub with your other and sprinkle it over the hen on all sides. Repeat with the other hen and place them both on the air fryer rack breast side down.
Once the airfryer beeps to tell you to add the food, place the rack in the air fryer. Turn the temperature down to 370.
After 30 minutes are up, flip the birds breast side up and continue cooking for the 10 minutes still on the timer. The internal temperature should read 165 degrees F, if it needs more time add 3 minutes.
Let the birds rest for 10 minutes before cutting into them.
