The kits are the latest additions to the beaver family in the enclosure at Sculthorpe Moor, near Fakenham.
Volunteers first discovered the arrivals last week before spotting the tiny pair with an adult female at Sculthorpe Moor yesterday (Thursday, June 9).
A spokeswoman for Hawk and Owl Trust said there could be more kits in the enclosure that have not been spotted yet.

Liberty Wells, digital communications and outreach ranger for the trust, said: “The staff and volunteers here at Sculthorpe Moor are delighted to have spotted two new additions to the family of beavers within our enclosure.
“It is such a positive and exciting time for the project, and it is lovely to see the two beaver kits on both camera trail footage and in person.”
The first adult beavers came to the site in 2021, and the family has since grown making the space an “amazing habitat for all”.
Ms Wells added: “Watching the family unit interact with each other is sweet, with the older kits showing the younger kits the way.
“The ever-changing landscape within the enclosure is amazing to see as they are shaping the wetland habitat, which then benefits the wider ecosystem.
“We are excited to see what the future holds for the project.”
