I'd guess partial molt, look around her neck for pin feathers.
Or she could just be taking a break, they do that.
Stress of unwanted amorous attention and new birds in the flock could also be part of it.

Chickens molt and grow a new set of feathers 2-3 times before around 6 months of age, those are called the juvenile molts.
Some pullets will have a partial molt their first fall/winter.
Most birds will have their first full adult molt their second fall/winter.

She does have some pin feathers coming in on her neck, but doesn’t have any feather loss there..
I did notice she is losing quite a bit of those half downy/half smooth feathers... they’re all over the coop floor in the morning, so very well could be kinda molting even though she seems to be past the juvenile molt and we’re just entering spring. Thanks!

Mine did the same thing, after we lost a roo she sat in the nest box 24 hours, then slept in the next box for 3 nights. She lost lots of feathers, I was so worried. Now she’s grown some nice new feathers, she’s around 12-18 months. However feather loss can also be a sign of illness so I’d pick her up and check her .

Aw, glad yours is doing well now. Mine is super friendly so I’ve been able to pick her up everyday and feel her abdomen, crop, look at her feathers and she seems to be completely fine but I’m definitely keeping a close eye Could have been stress induced like it sounds like yours was
