Ceramic Clock

I was given some of my Aunt's collectables, this ceramic clock was among them.  It is about 9" tall, weighs about one pound.  It has a windup mechanism but it won't turn.  Other than that I don't see anything wrong with it, looks to be in excellent condition, very clean, nothing broken.  The clock face had gold Roman numerals.  There is a bird's nest in the lower left corner with 2 baby birds and the Momma blue bird nestled in some vines.  I know nothing of the history, no markings on the clock other than the word "Minxie" just under the Roman numeral XII.  Picture is attached.
