Hi,
I started to notice a change in one of my budgies. I first started to notice because he seemed to be sleeping more than usual. What I also noticed was different was that he wasn't tucking his head the way he usually did. When he sleeps he just turns his head a little to the side but doesn't tuck in his head towards his back like he used to. He is also not standing as tall as he usually did or as his other budgie friends do. I have unfortunately had previous budgies that have become sick so I am really nervous he might be sick too. He is still eating normally. I attached a picture of him. Any advice would be incredibly helpful. Thanks!
