How intense is your pecking order?

[No Coop No Problem]

The size looks good! I definitely think with lots more clutter they'll feel more secure and won't pick on each other as much. If you have any lawn chairs you don't use, dog crates/houses, buckets, large pots, branches, ladders/step stools, stuff like that, use them! They can be used to escape under and behind and on, but also to hide enrichment items, food and water.

This is good advice. There's a lot of places in this world where people are comfortable with one another only because they can't see one another- because of walls, trees, fences, etc. However if those visual blockades weren't there then conflict would happen

I personally have around 50 chickens of all ages outside right now and they're not violent with one another. There's no chasing, feather pulling, fighting or injuring each other at all. Violence is not natural behavior for chickens other than mature males competing over resources. It sounds like your chickens are having stress-induced behavioral issues

Most of my flocks have had minor issues that went away once everyone started laying. If they didn’t go away or got consistently worse, I removed the worst offender. Sometimes just giving the whole flock a break from a mean girl for a day or two can reset the pecking order.

Compare it to teenagers finding out where they fit in in the big scheme of things. From my experience, unless someone is getting injured, it is best to let them work it out. My hen who is the lowest in the pecking order is also the only hen to sit and hatch eggs, so she is respected more now, not for her ability to stand up for herself, but for her fierce momma skills. We do have 3 roos to 32 hens, and they do help, they will put an overly bossy hen in her place.
