Hello, I don't know if this is the right place to post this question, I am sorry if it isn't. Thing is I am about to buy myself my first african grey, but the person who is selling it sent me a video of the parrot and it looks a bit different than what I've normally seen. https://youtube.com/shorts/_GgbSYXXiYA Can someone more experienced tell me if this looks healthy? I don't want to buy before making sure everything is alright. The client said it is more rare and wants to charge me more for it. But I don't know what to believe.
