Wii Poke Ranch question

[Goddess Lia]

Okay a friend of mine has the ranch and is at 500 poke right now.
I know we have to get to 999 i think it is to get the mew.

Now does Hayley Give more than one mew if we remove one poke and replace it with another or start all over again..???

You have to delete the My Pokemon Ranch save data in order to get another Mew. Naturally, if you do this, you will lose all pokemon in the ranch. (I get around this by having two games each holding ~500 pokemon. I send them to the ranch, get Mew, return them all to their games, and delete the save data.)
