Nigeria's The Daily Times said the arrest was made during the weekend at the Murtala Mohammed International Airport in Lagos while passengers were being cleared on a Turkish Airline flight from Sao Paulo.
Officials estimated the street value of the cache at $15 million.
Drug agents identified the suspect as Vincent Chegini Chinweuwa, the newspaper reported, who told them, "It took me three days to pack the cocaine inside the chicken. I was confident that the drug would not be detected. I have been living in Brazil since 2006. Life has been stressful because I cannot even visit my wife in Nigeria due to lack of money. I wanted some money to start any business of my choice back home. Unfortunately, I was disappointed upon arrival in Lagos."
