Is it okay for my chicken to sleep like this?

[OhDangBro]

My one chicken(Easter egger/1.5 years old) sleeps standing up on and off. I’m wondering if this is okay. Some days she seems to sleep later than the other chickens. She seems normal and healthy though she hasn’t laid an egg in a couple months, I think due to her going through a pretty heavy molt.

her pin feathers coming in might be preventing her from sitting properly

Chickens amaze me with their sleep habits, I’m thinking it’s normal if everything else is normal.
They can huddle into a ball when they tuck their heads under their wings. Interesting
