I have two green budgies: Male and Female. I came home today and went to go check on my birds. However, once I checked that inside the cage the male budgie was at the bottom of the cage, and it had puffed up feathers. Then when I reached my hand in the cage it went on a perch. It was still puffed up and standing on one leg. The top of its head was also strange, as the feathers covering the head were uneven.
What should I do? Is my budgie sick? I'm very concerned for my budgie I don't want it to die
