Exmoor was chosen after tracking data from released eagles showed the area had often been visited by several of the birds.
The species at one time bred along the Exmoor coastline, which continues to provide ideal foraging, including an abundance of fish, and breeding habitat for the birds.
Earlier this year, the six young birds were collected under a NatureScot licence from the wild in Scotland and brought to Exmoor.
Zoe Smith, from the Roy Dennis Wildlife Foundation, said: “We’re restoring a native species that should be here and has been removed from the landscape.
“We have a lengthy consultation process before we’re granted a licence.”
She added that the scheme only removes one chick at a time from nests, and the birds are checked for bird flu before they are released.
