Should i be concerned? My young 3-4 month old lovebird suddenly does this, I think its coughing up food, but she s(i think a she, didnt get dna check) too young to be hormonal and doesnt have anyone to feed. Im most concerned about the head shaking. I ve never seen a bird do that, what is it? She was doing this for a solid 3 minutes straight and a few times after that. What is it?? She s never done this b4. She seems fine now, but what is it??
