Hen losing feathers - normal? Help!

[Shellbiey]

Hi everyone!
I have five red egg layers, all born about April 15th. Two weeks ago, we noticed one was missing her tail feathers. She had no injuries, so we let it go.
Late last week, we noticed the back of her neck was missing feathers. No sign of attack, but the feathers were on the ground. It seems where the rooster grabs for breeding, but none of the other girls have this.
Today, she looks a little more naked on the neck, and is a bit lighter than the other birds. I have her inside currently to eat, drink, and watch. It looks like a molt to me, but this seems such an odd time to me to molt. We did see one hen peck at her this afternoon before we decided to bring her in.
She still hangs with the flock, and eats and drinks. She has spent more time in the nest box and coop, and I don't believe she is laying but only two of my hens are laying currently, so don't feel it's an issue.

The birds are free range, but are locked within a 20x20 fence at night and during snowstorms. They are checked at 2-3 times per day and fed corn and egg layer pellets, with the occasional eggs and expired produce.

I might just worried over nothing! If there's something I can do though, I want to!

That's a molt.

That's a molt.

Thank you so much. That confirmation makes me feel so much better!

Put her back out.
Some pullets will stop laying and have a partial molt their first winter.

They are checked at 2-3 times per day and fed corn and egg layer pellets, with the occasional eggs and expired produce.

Cut out the scraps and corn, stick with just the layer feed available all the time....
...or use an 18-20% all flock with Oyster Shell in a separate feeder.
