I've been turned off to sheep by the ones where I board my horses. First there was Frodo, a ram. He should have never been there. He was a pain, quite literally. I don't know how many people he knocked down B4 he left. No one was sorry to see him go.
Then there's another sheep-I don't even know if she has a name. She had actually belonged to the neighbor, but got out and made her way to the farm. They were unable to catch her to take her home, so she's been there for years. She decided that she liked the field that I have. I had her, and a goat in my field for several months. The goat was a real pain. I had to either stand guard so he didn't eat the horses feed, or feed him some cracked corn. Plus, they were both eating my hay. Once I got the welded wire fencing up in the field, I was able to chase them out. If I didn't already own goats, I would have been turned off to them as well.
Oh, and the sheep is a hair sheep, I just don't know what kind. And she is not friendly.
