Macaw new owner

[peppapul]

Hello, I have a macaw that was surrender to me a couple of months ago, apparently he/she is 30 ish years old and it is adapting well to my home, it was living in a 2by4 cage and now spend most of the day in my shoulder and my hubby build a new cage 12x4x6 for the times that it is not with me
But! It is regurgitating a lot, I only do head scratched and we are changing diet( it was only seeds and salted peanuts before!) and is hurting its wing
Any help is much appreciated! Thanks for reading

Do you know what happened to your macaws wing? It does look like in the video that it’s drooping. Is it bleeding at all?

Have you consulted a vet?

I hope that your beautiful macaw is okay!

Hi! It bites it's wings to regurgitate and then go on the floor and eats that... disgusting...
