Owl rescued from roadside, refuses to leave caretakers

These people were notified about a barred owl who was in the road and would not fly away. The woman immediately went to save it. They have made every attempt to contact bird sanctuaries and animal rescue organizations with very little luck. They allowed it to rest for the night and took it back where it was found for release. The owl refused to fly away. It eats, drinks and otherwise seems healthy. They made a perch in their barn and are hoping for the best!
