A pole shed and a Quonset...what do you think?

We're buying a little hobby farm and there is a pole shed with one stall and a giant Quonset. The Quonset has electricity but the pole shed does not. Which can we use for goats, sheep, or horses? Do people house animals in quonsets? Of course we'll need build stalls and such but just wondering what is recommended.

We have animals in both a quonset and regular outbuildings.  Please see this thread about our quonset and possibly get yours checked out for sagging and/or re-enforcement:  https://permies.com/t/49023/ft-quonset-roof-sagging-middle
Quonset's are not really ideal for stalls (unless the stalls are in the middle space?), but they can be made to work out.
