1 sheep, 2 sheep?

Hello all!

I have a question in regards to how many sheep is a good amount of sheep to start off with? I currently live in the DFW metroplex so I can’t/don’t own any animals at the moment, but I am researching into raising sheep for wool. I spin my own yarn and would like to have my own sheep one day. But I don’t know how few is to few? I know just having one isn’t a good idea, as they will get lonely and I wouldn’t want that. So I thought just having two would be an okay starting number. But the book I’m reading keeps saying 6 or more. That’s a lot. Much more than I think I could ever handle. So before I let my dream run away with me I thought I would ask, is having only two sheep enough or do I have to have more?

Thanks so much!
