I'm laughing quietly over Jock's comments. Bear in mind that my limited experience is with pigs, but some general principles apply to all.

It's work and takes up a lot more of your time and resources than you expect. It's never a part-time job.

I once met a fella who had a place in Michigan and had a small herd of some kind of black faced sheep and they were more of a conversation piece than anything else...he had the neighboring farmer, who had experience, on the payroll taking care of them. It got old fast and I heard that the guy sold 'em off a year into the project.
