Depends on the ferret - Unaltered ferrets are more solitary, while most ferrets that are altered like living in groups
Advice from another contributor:
Ferrets are very social animals and it is recommended that you at least keep two together, provided you can afford both of them. I have five, and they couldn't be happier. However, some older ferrets that have lived their entire lives alone may not like the company of others.
Domestic ferrets that have been neutered can live in groups - A group of ferrets is called a "business" Their ancestors - wild European polecat ferrets are solitary animals and do not live in groups
