The three males were filmed waiting on the roadside holding a Union Jack flag as they discussed their desire to leave France for a life in the UK.
Calais was the home of the infamous ‘Jungle’ camp which housed thousands of migrants until it was bulldozed and cleared in late 2016.
Speaking to three young males, a Sky News reporter asked the trio their ages.
The first of the men said he was 17, causing the reporter to say: “You look older than 17. You really are 17?”
The man, wearing black coat with the hood up, again replied yes.
A 17-year-old migrant in Calais was asked about his age
One of his companions, wearing a thick scarf and a grey wooden hat, was then asked the same question.
He said how he was just 14 and had been in Calais for a year.
The Government is facing a backlash after it performed a “shocking and devastating backtrack" by limiting the number of child refugees accepted into Britain under the Dubs scheme to just 350.
Refugee charity Care4Calais warned more unaccompanied minors were arriving to bleaker-than-ever conditions in the French port town.
But despite this, the Government announced that only a small portion of the anticipated 3,000 child refugees would be accepted into the UK from Europe under the scheme.
The refugee crisis charity called on ministers to reverse the cap as they accused them of "turning their backs" on child refugees fleeing "unthinkable violence".

A Sky News reporter to a migrant in Calais
Since the ‘Jungle’ camp was torn down, child refugees have been sleeping rough in the streets where they are at a heightened risk of being trafficked.
Sue Jex, head of UK operations at Care4Calais, said: "The scheme has been in place for less than a year, during which time the UK Government has failed to take in even a third of those children who were originally considered under the scheme.
"The problem has not gone away, refugees – including unaccompanied minors – are continuing to arrive in Calais every day, and are now living in conditions far worse than those of last year's jungle.
"We would urge the Government to rethink its decision and act now to urgently bring these children to safety."
Immigration minister Robert Goodwill quietly announced the cap on the Dubs scheme on Wednesday.

Last year a developed over the age of some child refugees who arrived in the UK from Calais.
Many argued the men arriving were significantly older than what they claimed.
One Tory MP warned Britain was at risk of being “taken for a ride”.
Philip Davies said the row over the real ages of supposed minors being brought over from the Jungle camp was doing "irreparable damage" to public confidence in the asylum system and called for tougher checks.
The Shipley MP said he had been contacted by a "large number" of people who had said "how angry they are that we're being taken for a ride" since his fellow Tory David Davies made a proposal to make new arrivals undergo dental tests to verify their ages.
However, the Home Office ruled out calls for dental checks to verify the age of Calais migrants as it was “inappropriate and unethical”.
