Last years chicks that they received all survived and were released...they were this small also!
The surrogate Moms do an amazing job!!!
From 2011 the video below is of their rescued barn owlets learning to fly in their flight cage.
Their storyEight few-months-old barn owlets were brought to the Northwest Raptor & Wildlife Center -- a Sequim, WA-based wildlife rescue and rehabilitation non-profit -- to be raised after being orphaned as small chicks. With the help of two barn owl surrogate moms who are permanent residents of the Center, the eight owls have all reached flying age and are being prepared for a soft-release into the wild.
