hay is primarily fiber, so any grass hay is about the same as any other ("cereal" hays like oat and wheat are a little different - with those, you need to remove the oats or w/e because the extra carbs are bad for bunnies). at your bunny's age, she could also have alfalfa hay - it's generally recommended for babies (under 7 mos) and pregnant/nursing mothers because it's higher in calcium and protein than grass hays. if you do decide to switch to alfalfa, though, you need to gradually wean her onto it rather than abruptly switching (just like switching pellet brands).
