Do not use oxbow for rabbits. It was not formulated by veterinary nutritionists and do not use timothy hay. It interferes with a balanced diet, don't listen to House Rabbit Society.
I'm not sure where you're getting you're information from, but none of this is true.
A balanced diet for rabbits includes 80% fresh hay, fresh veggies, and a small portion of hay based pellets. Unlike other brands, Oxbow doesn't add extra ingredients or dyes, and is trusted by well educated rabbit owners.

And both of these articles recommend the brand (along with many others).

Timothy hay is a great option for adult rabbits, as is oat hay, meadow hay, and orchard grass. Hay is extremely important for digestion and for keeping rabbits' ever-growing teeth down. Alfalfa is good for rabbits under 6 months old, but is too high in protein and calcium for adults and should only be offered as a treat.
Any veterinarian would tell you the same.

And the House Rabbit Society has lots of valuable information on owning pet rabbits. I'm not sure why you think it unwise to listen to them, seeing as you've provided zero reasons.
Also rabbits can't get sore hocks from wire floors as they don't have paw pads.
All of this is incorrect. An animal does not need paw pads to get sore hocks. Wire floors can be painful,
especially because rabbits don't have paw pads to protect their skin. So wire flooring can absolutely cause sore hocks and its best to just avoid it all together.
Yes, some meat breeds are bred to have thicker fur, and some people don't have issues with sore hocks while using wire flooring. But saying that it's impossible for rabbits to get sore hocks at all because they lack paw pads is just ridiculous.
For pets, it's more simple to litter train rabbits, so there's no reason to use wire flooring. Using a playpen or dog kennel rather than a wire bottomed cage is much more comfortable for the rabbit, is cheaper, and provides the much needed space anyways.
Before making absurd claims about rabbit care, please do your research so you don't lead someone to believe this misinformation at the rabbits expense.
