What do you think of animal planet fortified rabbit food

[tiabia0]

I've been giving Thumper BBT with a little bit of animal planet for the last couple days so he can get used to the new kind. When I give him back this weekend should I have the women do the 3 week thing with the 2 foods:

FIRST WEEK: 1/4 new food, 3/4 old food
SECOND WEEK: 1/2 and 1/2
THIRD WEEK: 3/4 new food, 1/4 old food
FOURTH WEEK & ON: all new food
