We don't, even though we have yotes. The goat houses aren't predator proof, and if something gets them in the house they don't stand a chance. We had a dog attack a couple years back and the house worked in the dog's favor.
We have big mama in the far pen and her horns are no joke. She doesn't take any attitude from other animals either.
The minis are in with the ram sheep, and he has horns but he's only about 85-95lb. He doesn't go in the shed as much as the others do. He ha a watch spot where he seems to take shifts to sleep and watch.
On nights when there is a lot of activity, yapping and howling yotes, they all stand watch.
There are 5 in their herd total, so the fuss they would kick up would be heard for miles. Between them and the dog, humans would arrive quickly.
Just the feed me yells at 6:30am have me jumping out of bed to make the noise stop.
