My rabbits are fed Mana Pro feed and I find that it keeps them in great condition. I use Mana Pro's Sho Supplement as well along with giving my rabbits a mixture of black oil sunflower seeds, oats, fresh fruits and vegetables for treats. They have access to unlimited hay and water.
I use an automatic watering system, which is a great investment, by the way! I highly recommend it. Cheap and not difficult to set up.
All of my rabbits are handled daily and are let into an exercise pen as often as possible.
My rabbits are housed in all wire cages
24x24in: Dry Does and Bucks.
24x48in: Does with litters and groups of juniors.
Each cage has an E-Z mat for them to rest on, which is important especially for Rex and bigger breeds, a wood block and some type of toy.
I do not regularly use trays as I prefer not to have my rabbits sitting so close to the ammonia smell. I let the manure fall into a built in pit and clean them out once a month or as needed.
My rabbitry barn is around 25x28ft. It has gravel flooring and is made of Yellow Poplar wood from the woods at my house.
It has a large sliding door in the front and a metal roof.
On the left wall there are two windows to allow for more air circulation and natural light. I have two box fans that sit in front of the windows to push air through the barn more.
