My Dad had a hen that befriended him . . . followed him around, cleaned off his boots when he stood still, hopped up on the fence to be petted, even got to him so much she'd ride around perched on his shoulder while he did chores. Spared her from the stew pot when her egg laying days were over.
She even befriended his border collie . . . we can't figure out how other than guessing that border collies are so smart they figured any friend of my master is a friend of me.
