The Legend of Zelda: Ocarina of Time 3D Easter eggs

Cucco in Kakariko Windmill
As adult Link, once you have beaten the Water Temple and got the longshot go to Kakariko Village. Get past the cutscene and then use the longshot to get on top of the blue roof by the guy. From here you can longshot onto a small wooden stake in the lower windmill opening to reach it. Now go up the stairs and it will lead to the higher opening where a cucco is. No real point to this though.
