Falbi

Falbi is a former circus actor who now owns Falbi's Flight by Fowl at Lake Hylia that allows you to fly Cuccos around over the lake. If you throw all his Cuccos off into Lake Hylia he will exclaim "Whu, where did all my Cuccos go, well I guess you'll have to learn how to fly by yourself, partner".

Falbi's Mystery
After freeing the cuccos in Kakariko Village if the player transforms into a wolf and talks to the white cucco he will say that his previous master mistreated him so he ran away, but he likes it much better at Kakariko Village. Now, if the player brings the gray Cucco to where the Goron is keeping watch and talks to him as a wolf he will say that the other Cucco flew in from Lake Hylia. As Falbi is the only person at Lake Hylia that owns Cuccos it is obviously him who mistreated the white Cucco. However, none of the other Cuccos that Falbi owns complain about how they are treated; in fact they seem quite happy in life. Why the white cucco said this about Falbi is unknown.

Trivia

 * One of the cuccos in Ordon Village mentions a legendary place in Hyrule where cuccos can happily flap there wings all day long. The cucco is obviously refering to Falbi's Flight by Fowl.
