My bird can't fly anymore
I have a hand raised major Mitchell who I've had since he was a baby. For his first year he could fly at all. I assumed it was because the first wing clip he got before I bought him wasn't done correctly. The feathers just wouldn't grow and when he tried to fly he would constantly fall and the wing would bleed, hence prolonging the new feather growth further. This caused him, and us, a lot of anxiety and I believe caused him not to trust us.
Then, finally his wing grew and he could fly. He doesn't fly great distances, but could control it. He could fly from his cage to the ground and land without crashing, or fly from his cage to his playground. This lasted about 6 months to 1 year.
Now, for the past few months he has gone down hill again and can no longer fly. When he tries to fly it's like he can't control himself and does a back flip. This happens when he is trying to fly to leave his cage, or when he is on the ground and wants to fly. He then panics and does 3 or 4 backflips ( not very elegantly) and crash lands.
He is with an eclectus who is a very calm bird and can fly and be handled without any issues at all. They are great friends. I can barely handle my major Mitchell anymore without being bitten. He has a diet of mixed parrot seed, and fresh fruit and veges. Do you have any suggestions or advise.
