Another reason I can't adopt is the fencing requirement. I have seven acres with chicken coops spread across it; I need the dog(s) to cover it, not just a backyard. I'm not fencing seven acres. It would cost thousands and thousands, plus I already fenced for horses (and spent thousands and thousands on that already). My small farm friends with LGDs use the Stubborn Dog fencing kit with great success.
Hens go broody when you don’t want them to… and won’t go broody when you do.
