I have tried a lot of different hay , small pet select ,oxbow , kaytee . The small pet select in particular does seem fresh enough but my buns are still so picky . They are 6 months old ( neutered but not yet bonded ( stay tuned lol)!! Any how I fill their bin and have also put it in tubes to make it fun to eat . They just seem to LEAVE SO MUCH of it . I hate to change it out every day - cuz they go thru it ridiculously fast . As long as it’s clean I leave it in and just add to it for a while before I change it out . I’d like to hear what other people do with buns that don’t eat much of their hay . ( ONLY give them a little at a time and switch it out every day ?..... Give them a lot and let them have it for a few days with the thought they will eat their favorite first , then start picking from what is left ? Or buy the 50lbs at a time and just change it every day and waste a ton ? They seem to like to pull at it and bit it in half but not eat it so much !!
