hello everyone, my name is amber, and I just recently received a beautiful B&G macaw (last week) she belonged to a neighbor who had her for a few months, and he got her from someone else. it was basically love at first sight with us. lol the first night I met her she came straight to me and wouldn't leave my shoulder. when my neighbor went to grab her she would run away from him haha...well now he's moving and they don't allow birds, so now she is with me. the first two nights I had her she was an angel. I taught her to wave and give kisses and make the sound afterwards. I'm starting to get concerned. yesterday while eating breakfast she regurgitated on my shoulder twice. instantly I thought something was wrong so I googled it. now knowing what it means since then she's been different. she's not doing her tricks, she's having an attitude with everyone including myself. she hisses at me a lot now. but still comes to me when I go to her cage. when she is on my shoulder she gets mad and head butts me if I move my head and nips at my hair. but at the same time she just got off her cage and walked over to me to where I'm sitting. So my question is..am I doing something wrong? is there a way to fix this? someone please help me. thank you ahead of time
