I'm considering Shetland sheep, but I have a few questions. When I say sheep I just plan on one to supply my wool crafts (it will have other livestock for company) so probably a wether. Is it ok to keep an ewe without ever having her bred or will that cause problems? I like Shetland wool a lot, but it really seems go through drastic color changes as they age. I get the idea from local Shetland owners, and maybe this is wrong, that you can't buy a white Shetland and expect to have white wool for years to come. One year it will be grey, then brown maybe, then white again with spots of black, etc. Many of the Shetlands I've been around also have been timid to the point of imbecility, which in addition to the ever varying wool makes me hesitant about the breed. I know sheep aren't brilliant, but when they run and hide in terror every time their owners enter the pen to feed them, it's a bit much. So any enlightenment or wisdom on the breed would sure be great. Thanks.
