Behavior change inquiry?

[Sarcastic-leo]

I've adopted my sisters lonely gander since we first met we've been friends , (thankfully) so I've been learning and going with the flow lots of internet searches and so grateful I've found this site. Everyone here has been so helpful and kind much appreciation.
Now for my new inquiry , when geese (my 1 & only gander ) molt is it common for them to become lethargic and depressed in the medical sense? Now I can totally understand his current state of irritability I would be too shedding those feathers and getting in new. I imagine it would be like a pesky ingrown hair. Eehh.. now he had a scuffle with his OG mom when she came to visit, but he was a little sad before that but seemed to get even more after that incident, even after she left he shunned me for about an hour so I gave him his space then interacted with him as normal though I did tell him he was the best and most handsome gander in the valley a few more times than normal...lol
Also he was laying down in a strange fashion the other day he had one wing stretched out half way and on the opposite side was his leg half way stretched out bottom of foot side up. I've just never seen him lay like that b4? Your thoughts opinions or factual info will b greatly appreciated. Thank you just me and a lonely gander named Goosifer.

Sometimes they stretch just like we do. I've seen that one before. Molting can be a sensitive time for birds so just try to keep them healthy. Otherwise if this is a pretty severe molt you might want to check down to the skin just to make sure nothing is going on externally. My chickens have had much tougher time with molt than my geese have.

Otherwise I'd say he needs a goose friend.
