Here's a silly question. I have yet to get a border collie but I would like to get one to help me control my flock of birds and also my goats and keep them where they need to be. I have an acre and it is all fenced with mostly split rail covered in chicken wire. I was wondering if a well trained border collie would hang outside all day doing his job instead of say running off. I know they are dogs but I know they can be [retty committed to their work. That being said my hound mix and my lab mix will be gone in a flash if I don't keep an eye on them because they know how to get over the fence. I assume they do it because they like to explore. I know border collies are high energy dogs but are they also explorers?
