jrbsr,
here are some updated photo's of my Ocellated showing what could be a 5th spur. NWTF is saying it is a "jake spur" and a biologist that studies the Ocellated and actually took these pictures and is studying my bird but was not aware of the extra growth until after he had the bird seems to think it could be an extension of a leg scale. so at this point until a biologist actually looks at it physically I don't believe we should count it as an extra spur. here are the photo's make your own conclusion.
