How to stop hens pecking and injuring other hens in the coop

[EggsNchooks]

Hi all,
So I went in the coop this morning and found this hen who’s been getting pecked. The culprit has pecked a decent sized deep hole in her back, I have caged her up elsewhere and put betadine on her wound. Is there anything else anyone can recommend to help her heal?

what can I do about the aggressive bird that’s attacking her all the time? They are all free range hens during the day so they shouldn’t be bored..

How much coop/run space do they have when you keep them in?
What do you feed?
How many birds do you have?
Keep the wound clean and apply triple antibiotic ointment.

This is their coop that they sleep in and every morning once the eggs are laid they free roam over a few acres. I have 13 hens and 1 rooster...

And they eat mixed grain with our food and vege scraps and pick at grass and bugs all day.

Sometimes pinless peepers on the bully helps, but not sure if you should put them on free ranging birds.

Could she have possibly gotten injured by rooster spurs or nails, then the others picking at her?
Chickens are fairly opportunistic, if they see an injury they will pick at it making it worse.
