1) Let the quest expire. 2) If you haven't done Popocho's Chocobos yet, do it now. 3) Get into a random battle at Targ Wood. 4) Weaken the Yellow Chocobo in that battle to critical health without debuffing it. 5) Get your Chocobo Knight to mount the thing. 6) Re-accept the mission. 7) Go to the spot. 8) ??? 9) Profit!
you need a chocobo knight and you need to see the choc in battle. when you get it in critical condition, get your knight to walk up next to it and mount it. then select the ranchers request mission and go there. select your mounted knight as the character to talk to the archer guy. then they take your chocobo away from you :( i know that you can battle 5 yellows and 1 red in goug at some point in the year. i dont when. sorry.
