The Cucco Shack is a location from The Legend of Zelda: Majora's Mask. It is, along with the main area and the Doggy Racetrack, one of the three sections that make up Romani Ranch.
Inside the Cucco Shack, reside ten Cucco Chicks that Link can entice to follow him by marching with the Bremen Mask near them. If Link gets all ten Cuccos to follow him, they mature into fully-grown Cuccos. After the Cuccos have grown, their keeper, Grog, will reward Link with the Bunny Hood.
