Molting or bullying (pics)

[MildlyOffensiveChicken]

Little over a year old RIR hen.

She gets picked on, irregularly. The run is large and the bully hens don’t follow her, rather take a peck at her head and she moves off. There are no wounds, the darkness on the back in the pic is dirt from bathing. I’ve separated here a few times, but I perceive the feather loss continues and she is agitated the entire time. If this is molting, it’s been taking quite awhile.

She lays around 4 eggs per week. Color has gradually lightened and there has been an increase In Calcium Coating. I recall she had some calcium coating issues in her first 10 eggs.

Is she molting? Is she getting defeathered by the other birds?

She is being feather pecked/plucked by flock mates.

That is definitely not molting. Looks like she’s being bullied.

Do you have a rooster? Have you observed the other hens dominance mounting her? It looks like not only picking but wear from being stood on during mating.
