The saga of Rottie the Rat. Is it for real, who knows? I did read an account once from years ago of a great-horned owl imprinted on chickens. It even got to the point where the farmer that owned the owl started giving it chicken eggs to incubate. When the chicks would hatch there were a few awkward moments of the owl trying to feed them meat, but the chicks just ignored it and pecked away at grit.
Which reminds me, Phil Harris' singing "There Ain't Nobody Here But Us Chickens" is one of the best songs ever.
