My female bun has been with us for a week now, and she doesn't seem to be eating that much hay. She goes up to it and eats for a few seconds and then she leaves (unlike my other rabbit who just sits in his litter box and eats for almost hours). To me it looks like she's being really picky with the hay. I don't really want to change brands because my other rabbit loves the current one. Is there a way to get her to eat more of this hay? We did get some of her old hay from the breeder if that helps.
