Raising of a Great Horned Owl

Two baby great horned owls fell out of the nest at 7 days old, one was dead. The living owls eyes were not even opened yet. We cared for him for 2 weeks and then took him to a rehab facility. We think he had a couple of strokes from the 50 ft fall.
After 3 weeks I picked him up because they have to relocate where they fell. I put the owl in an old nest about 20 feet up in the tree. The mom and dad came over to the tree to watch over the baby, we were so happy for them getting back together. A couple of days later the baby was screaming for food on our porch. We tried hard to get him back with his "family". Apparently mama isn't feeding him/her. So I made a feeding table with a perch to keep him off of the ground and away from other animals and off of my deck and furniture. He's hunting worms now and eating live prey, hopefully he will venture out soon.
