Goats are great, I used to breed milking goats. They also need drenching regularly and they need their feet trimmed often. They need a lot of roughage in their diet to keep them healthy and to stop them eating stuff they shouldn't. If bored they will ringbark trees.
You can teach them to walk on a lead and we taught them to pull little carts too.
None of ours butted people but you need to actively discourage this when they are young and not engage with them if they try and butt.
They can also be tethered if you'd like them to graze in you other paddock, this obviously requires planning and supervision but can be very successful for goats.
