This “chicken” might sing.

The former spymaster of Venezuela — Hugo Carvajal aka “El Pollo” or “The Chicken” — could end up being a star prosecution witness at Nicolás Maduro’s drug-trafficking trial, experts told The Post as they laid out possible defenses Maduro could raise.

Carvajal pleaded guilty in June to narco-terrorism, weapons and drug trafficking charges in the same case that Maduro was charged in.

He’s also being held at Metropolitan Detention Facility in Brooklyn — the same jail where Maduro is cooling his heels.

Carvajal flipped allegiance and backed Maduro’s opponent in 2019, and he’s already expressed interest in cooperating with the feds as he faces down the potential of life in prison at his sentencing — which is set for next month.

“This is exactly the type of person that would be a witness in the case,” former federal prosecutor Neama Rahmani told The Post.

If he takes the witness stand and testifies truthfully, he would get a “significant reduction in his sentence,” Rahmani said.

“The sentencing [in drug-trafficking] cases are so high, so you have to cooperate,” the lawyer added.

Dick Gregorie — a prosecutor who handled a similar US case against another foreign leader, Manuel Noriega, in 1988 — suggested there is a “good possibility” Carvajal will be a prosecution witness.

“I would assume if he had a deal that he made six months ago, that they have probably been preparing him for weeks, or months, maybe,” Gregorie added.

Prosecutors will also have “a number of internal people from Venezuela and drug dealers who were involved in moving the drugs” as witnesses, he said.

Carvajal, 65, a retired major general who was close to the country’s late president Hugo Chávez, was accused of using his office to help smuggle 12,300 pounds of cocaine on a plane from Venezuela to Mexico in 2006 and received millions of dollars from drug traffickers in exchange.

Chavez handpicked Maduro to succeed him but Carvajal eventually ended up supporting Maduro’s opponent, US-backed Juan Guaidó, in the hopes of a coup that never happened.

Carvajal pleaded guilty to four counts without a promise of leniency from prosecutors in a likely bid to gain their favor down the line.

Carvajal’s lawyer, Rovert Feitel said at the time of his plea, that the feds didn’t offer a deal or reach out for negotiations.

“He has information that is extraordinarily important to our national security and law enforcement,” Feitel told the Associated Press at the time.

Gregorie said the case against Noriega — who received a 40-year sentence in 1992 for drug trafficking, money laundering and racketeering — will likely be used as legal precedent in the case against Maduro.

Maduro, 69, was captured in a military operation Saturday alongside his wife Cilia Flores in the sweeping case from 2020 accusing him of using his allegedly illegal government to work with dangerous drug cartel’s — like Fuerzas  Armadas Revolucionarias de Colombia (FARC), the Sinaloa Cartel, the Zetas, and Tren de Aragua — to move thousands of tons of cocaine into the US for over a decade.

Maduro will likely attempt to get the case thrown out on the grounds that as the leader of Venezuela he benefits from sovereign immunity — a similar argument that Noriega tried to raise. 

Rahmani said he doesn’t think the argument will gain legal traction because the US doesn’t view Maduro as a legitimate leader and courts defer to the State Department to make such a determination because “it’s considered a purely political question.”

Maduro’s team could also try to argue that he was unaware of the drug-trafficking taking place in his government right under his nose. But the legal experts suggest the feds will certainly have evidence — including cooperating witnesses — to rebut this argument.

Maduro could also try to claim his arrest was conducted illegally, through violence — an argument that Noriega also raised, Gregorie said.

“There is an argument that he shouldn’t have been brought in that way,” the former prosecutor said.

And Maduro could try to pick apart the case to see if there was anything illegal about the way that evidence was collected, for example, whether the feds followed Venezuelan laws to the letter on how wiretaps can be used, Gregorie said.

“I think this is likely a slam dunk because this is an older indictment,” Rahmani said.  

“It had to go through a lot of approvals. It wasn’t just front line prosecutors in New York… You had, very likely, the Attorney General of the United States at the time, signing off on this indictment.”

Maduro’s wife Flores and his son Nicolas Maduro Guerra were also charged in the drug-trafficking scheme. 

Maduro and Flores both appeared in Manhattan federal court in the Southern District of New York Monday where they emphatically pleaded not guilty. Maduro also claimed he was “kidnapped” and was a “prisoner of war” at the end of the hearing.

He and his wife were held without bail and they face up to life in prison if convicted.
