Gather each individual crazy chicken, bring it to the pen, and chuck it in there. To obtain it, you need to help the distressed woman standing in front of the entrance to the Kakariko Graveyard round up her errant chickens. The super convenient bottle item is a must - it's handy and lets you carry potions, fairies, and other things. It is highly recommended you take the time to tackle a few of these right now. While you can skip Kakariko Village and head straight to Death Mountain, you would miss out on a bunch of cool side activities, including getting the Hylian Shield and an Empty Bottle. The long stairway to Kakariko Village is located across the bridge to the east of the castle drawbridge.
