Half of my lovely rabbits are free range outdoors and half are indoors free range. The amount of space you're going to give them sounds fine. They LOVE to dig, make sure they can't dig out because they will. Give them lots of hay, vegetables...fruit to be given sparingly and as a treat. High quality pellets are a must as well.
Litter trays can be used, my indoor ones use them and it's adorable lol. Find the corner they litter in the most and put a tray in that spot that they can easily jump in and out of and fill it with newspaper and hay.
Mine LOVE cardboard boxes to sit in, chew, rip up, throw around, it's so much fun watching them play in them as well. Whenever/ if ever you get something delivered from
Amazon, keep the box and give it to them, they'll love you for it. They like wooden toys, balls with a bell in. As another poster also said, I have chairs outside that my rabbits love to sit on.
Water - they can drink from a bottle or a bowl, although bowls can get knocked over and tipped if not ceramic/heavy, they can also become dirty fast.
As for bedding, use Straw - shavings and saw dust are dangerous if inhaled. Put newspaper down first then straw, that will provide extra insulation if needed. If you have no grass, you can grow it in tubs/pots/large dog baskets and let them feed on it. If no soil, do the same thing with that.
As for pairing - two is always best. Rabbits can fight and it is always nasty when they do. Best pairings are boy and girl or two girls. Get them spayed and neutered although getting the boys done is a safer option - they do better under anaesthetic and its a quicker operation therefore lessening the time under.
Check for any fighting and if you see it immediately separate them.
Predators - foxes (as well as other predators) can and will choose your rabbits for their dinner so ensure cage and run are completely predator proof. Rabbits are sturdy and fast but 95% of the time they cannot win against a fox. You may go years without having an issue and then one night it happens (trust me). If you think it's might not safe, or 'it looks alright' - it's not safe at all.
Cold/Warm weather - Rabbits grow an extra layer of fur in the winter which provides them with excellent insulation. They then lose this layer come spring/summer. They do better in the cold rather than the warm so when weather is hot, ensure extra ventilation and use ice treats/ice cubes with veggies in to help them cool down.
Routinely groom and check their bottoms for any mess and their feet for any sores etc. ONLY bath your rabbit if his/her bottom is messy and it won't come off with a cloth/paper towel - if you need to bath your rabbit only bathe their bottoms.
And PLEASE watch out for anything that doesn't look dangerous but can be e.g. drains/gutters with no coverings on, pools, ponds, large areas of deep water, unstable concrete slabs, bricks etc. I know it sounds silly and common sense but some people don't think of these things and have lost rabbits to them.
Hope this helps, any more questions feel free to ask, rabbits are wonderful animals, they each have their own characters/personalities and love human company as well as their own
