Sheep that speaks the day of your death

I once heard a myth which went along the lines that somewhere in the North of England there was a sheep (or other animal) which, if approached at the correct time (probably midnight) and date, would speak the day of your death (I’m not sure exactly how it went though). Unfortunately when I’ve tried to find out about this my searches have drawn a blank. Does anyone know of a myth like this, or did I just imagine it?
