To obtain The All Clucking Cucco side adventure in The Legend of Zelda: Tears of the Kingdom, speak with Penn at South Akkala Stable during the Potential Princess Sightings side adventure.
For this quest, head up to the tree on the hill to the right of Penn and speak with the all-knowing chicken. Cucco will want you to complete trials.
For the first trial, you’ll need to reach the top of the stable’s head within the time limit. For this trial, Ascend will be your BFF! Quickly run inside the stable and stand in the center then use Ascend. Once on the roof, use Ascend again on the horse’s head to reach the top.
For the second trial, you’ll need to bring 3 logs to the hill within the time limit. Quickly run straight ahead then chop down 3 trees. Use Ultrahand to attach them all together then use Ultrahand again to lift them to the chicken at the top of the hill.
For the last “trial”, you’ll have a surprise fight against 3 Yigas! Eliminate them all so Penn will show up. Afterwards, the quest will complete!
