I agree,you should also try and inclued a run of some sort with your hutch.Ferrets are far happier in a ferret court than a hutch.Put some logs in ,rocks,pipe anything helps you dont have to spend alot of money,in fact one of my hobbs will destroy anything shop brought (hammocks etc) he now has a transit tyre and loves it lol.
If at all possible never keep a ferret on its own IMO they are far happier in groups. Good luck
