We still have three chicks, which are now about ten weeks old and we expect them to fledge sometime this month.

Children from Beckingham Primary School visited the Willow Works in October to watch the owls and dissect some of their pellets.
Students from the University of Lincoln have also been diesscting their pellets and discovered the skull of a water vole in one of them.
