Area: Geothermal Valley
Camp: Valley Homestead
If you are finding it difficult to throw and shoot the chicken (as I was), you can use a glitch that occurs with the chickens to make this achievement easier. Once you have captured a chicken, you can then release it (press B), and the chicken will flop around incessantly in place. If you drop a captured chicken in a place which is off the ground (like a box, steps, or crate) the game will recognize it as “in-the-air.” There is a box-step on the side of the building near the stone steps where the chickens spawn near the camp. Drop one there, step back, and fire away.
