I'm a new rabbit owner and I wanted to be economical and buy hay by the bale. I bought one from a feed store about a half an hour away from me. It was $20 for a 40 lb. bale. It doesn't look or smell as nice as the Kaytee timothy hay I had originally purchased for my bun. Can anyone tell me if this is usable, good hay? There are also a lot of these floral weed looking things...
