Hmm, she doesn't officially have a name in Ocarina of Time except the Cucco Lady, but she's named Anju in Majora's Mask, even though Anju doesn't have anything to do with cuccos, but then in Minish Cap she's got cuccos again and is also named Anju, so I guess it's safe to assume her name in Ocarina of Time was also Anju and was just never mentioned, and I'll just tag this Anju.
