Quick housing question....

Would a 4ft double hutch be okay inside a shed, for four buns to use nearly always as a 'shelter'

They'd only be shut in it for about 20 mins a day while I clean litter trays and tidy the shed.

They wouldn't be permanently shut inside it

Don't see why not myself, it was what I was planning on doing for the lions when we were thinking of getting a shed for them.

Agreed. If they have access to the rest of the shed all the time and will just be using it basically as a sleeping box and base, I don't really think it matters what size. IMO you could even use a small single hutch or a dog kennel, just anything that provides a cosy sleeping space.

Oooh you could make the entire top level a sleeping box, just pop some towels/blankets over the mesh and fill with hay! Sooo cosy
