Building muscle for flight

[EclecticSoul]

So Trucker has been with us for over a month, he is eating a good diet now, about half veggies/fruit and half harrisons high potency pellets, with assorted nuts added every day, and a bit of whatever we might be eating at the time. His feather quality has greatly improved and he has had a vet check. Everything is going great aside from the fact that I have no idea how to get him to build muscle strength so he can fly. He has always been a flighted bird, ever since my husbands grandparents got him as a freshly hatched bald chicken. My thought is that since he was pretty much cage bound for his first 14 years of life, maybe he never learned how to fly?? Is that possible? Right now anytime he tries to fly he just ends up going straight down. Makes me sad. So how can I get him into condition to be able to fly?? Obviously he would never be able to fly outside without being secured on a harness.

The same thing went with my family when we got Mozzi. He didn't know how to fly, but his cage mate would fly around the house. Mozzi is training himself how to fly. He use to just fall to the floor when he tried to fly, but now he can up to 10 feet of flight.
