Donkeys are social creatures . They bray a lot if they are alone , which is why the donkey sanctuary boards them out as pairs .
They will need a field shelter that they can enter and exit as they wish .
You need to have a farrier who will give them the proper foot care as mentioned .
I’d say you’d need at least a few acres , so that you can “ rest” paddocks as needed .
They are wonderful animals . When I win the Lotto , I will re-home a few pairs from the Donkey Sanctuary . At present I can just about pay to keep 1 horse .
