Not at all the choice is up to him but I would still keep a bedroom in the cage for him sometimes my boys sleep in there sleepy ball and sometimes not ..I was told to provide a nest box/ sleepy hut for them as in the wild Quakers usually sleep in a nest .
My boys have a jolly ball its plastic and can be washed easily, or if your cage is too small you can use a big PVC pipe and hang it hig in the cage with access via a perch or a boing....
This is my travel /emergency cage with a PVC pipe sleepyhole...

and here are the boys with their Jollyball ...they each have their own...But play together in one during the day when their cages are open...(size is 10inch)


here is a link to many different tents...
