Spring Molt? (Pictures included!)

[kherokee]

I have a little frizzle pullet and she's always been at the bottom of the pecking order but all of a sudden i've noticed shes missing feathers along her back and wings! I was thinking overbreeding by one of my roosters possibly but I haven't seen her lay an egg since winter so I'm thinking molt? I dont know if spring molting is a thing since it's march but

I checked for bugs on her but I found none and her vent it perfectly clean.

Unfortunate Update:

The flock excluded her from the coop - I found her sleeping on a chair next to the door so I brought her inside to the "chick nursery". We'll just play this by ear for now
