I’m officially worried about Hao-chan. There is something… off. He doesn’t seem specifically ill. But:

• He’s stopped hopping up and down. This is something he used to do every day while singing. But he hasn’t done it at all for a while. Somebody mentioned that since he’s molting it might just be that, but I don’t remember any prolonged periods in the past when he wouldn’t hop up and down a lot.
• He doesn’t sing much anymore. He never sang a lot, but he definitely would multiple times a day. Now days can go by without him singing.
• Most worrisome is that he seems to sleep all the time. Like in this picture – he’ll land on my finger but then almost immediately go to sleep. 
• He doesn’t seem as feisty as usual.
