Go to the Amazon Forum!
The second of two sticky Threads at the top of the Amazon Forum: I Love Amazons ....
Open that Thread and look at the listing of Segments listed. One of they will include the word: "refledging" Click on that segment and it should take you to it. If not scroll down until you find it!
Remember, that the process of "refledging" must include your Avian Vet as you will be stressing Lungs (air sacks) heart and flight muscles that have not been used for flight! You want to assure your Avian Vet fully understand the load you are about to place on your Amazon! Assure your Avian Vet complete a full spectrum blood test and that all organ chemistry are proper! Heartbeat at rest and with some mild stress, (the visit itself will cause that). You want to hear that Heartbeat rate! As "refledging" activities STOP if you hear it!!
Are your Amazon's full flight feathers in place, including its tail feathers?
After you read that Segment a couple of times, please come back with questions!
