ok so im in a little town in kansas and spring is on its way!(was at least) and i was wondering about letting dear little Herby out to enjoy the fresh air( i have a nice section where i used to let my rabbits run around, its off to the side out of the wind and in the shade) now i dont have any idea what grass will do to a chinny, and thats kinda a big part of my yard so exclude: dogs, cats, toxins, random peices of wood and what not, i would clear all of those out of course and the place is durable and high (i may put a roof on it just in case though). would that be acceptable? also i used to let my rabbits explore outside on a bunny walker, it was a harness that went around their neck, under the stomach and the hook for the leash is on the top, would i be able to use that on him? advise and knowledge wanted and very appreciated!!!!
