Dorpers jumping through fences
I'm wondering if someone can help me.
I used to own what I believe were Poll dorsets and had no issues except in finding shearers to come out for such a small flock of only 5 sheep.
Recently, I sold the 5 Poll dorsets and bought 5 dorpers so shearing wouldn't be an issue, but now find they're jumping through and over my fences into other people's properties.
I'm wondering if someone can recommend sheep breeds that are good for keeping grass down, and don't have a tendency to get through fencing? Preferably a breed that sheds it's own fleece naturally.
Or is there another type of animal that is good for keeping grass down and doesn't need great fencing to keep it in?
Many thanks and season's greetings to everyone.
