Wow! Thanks so much! I've been racking my brain over it for so long! Definitely not something I was expecting to see here lol

Interesting. Wikipedia doesn't even mention them having been introduced to Europe but I guess it makes sense. It was just walking around, no fence or anything!

Np, some people keep them with their chickens here in Aus as a deterrent to foxes. Not sure how well it works.
