Bosnian love magic: Blood of a dead chicken

A chicken egg is buried into horse manure and is left there for 21 days. After that the egg is dug up and in it, according to folk belief, a chicken will appear. The egg is cracked and the chicken is slaughtered with a gold coin. Using its blood one smears a body part of the person whose love one craves. Of course, this needs to be done discretely so that the person doesn't notice anything.
