Like the eagle in the United States, the blue peacock is the national bird of India. It follows then, that like the USA, India also made killing peacocks illegal. In the USA, you cannot have feathers from their national bird. But in India, you can have peacock feathers but only if they are naturally shed. To find out if a feather is naturally shed or if it was plucked from the skin of a bird, authorities simple place the shaft under a fairly low magnification to examine the base of the shaft. They also use their technology to perform a simple chemical test.
