Wifey raised and bred Netherland dwarfs for years (though she would not let me eat them).
Keep the food (pellets) available at all times.
Rabbits make great "composters" for kitchen scrap which in return, produces one of THE BEST FERTILIZERS !

PLENTY of water.
Water bottles are fine but need to be filled regularily, sometimes daily depending on bottle size.
We got the nipples that fit onto 2 litre bottles so we could replace/recycle often..
Clean nipples or algae builds up.
Our pens were 3' x 3' x 5' ( designed to best utilize 1/4 mesh) about 2 ft off the ground and each held several rabbits.
The 1/4 mesh helps keep rats out of the food as Rabbits and rats get along (same genus).
Roof was pitched plywood with an elastameric coating.
Doors were vertical sliding plexi.
A wooden box with nesting material (hay, newspaper, rags) was provided for EACH female.
