Bully only picking on 2 chickens

[McChooky]

We have 6 chickens in an enclosure that is 6x11 and plus their coop is 6x3. They have plenty of room plus we let them out for 3 hours a day. They are all the same age and our Legbar is sweet to all except the Easter Egger and Sussex. She will pick on them. We have put her in Chicken Jail by putting her in a dog kennel inside the run for a week We have put the chicken blinder on and squirted her with a water gun. Nothing changes. It’s only these two. We have a Silver laced Wyandotte who is the Queen, a Polish middle in the order and a Brown Cochin the lowest. She won’t bother any of them. Any suggestions? I added a photo of the coop and run They have a dirt bath and plenty of places to hide For now we are just keeping the Legbar separated View attachment 3294876

By adding an extension on front ( blue section) you could double the size of their run.

If the aggression is while they are in the coop portion, how many feet of roosting bars do they have? Can you post pics of the inside of the coop and run? If the aggression is in the run it could help to add more clutter in several levels so they can get away from the bullies. The is thread may help with some suggestions:

How many feeders and waterers are in the run portion? Are the out of line of sight with each other?

Is the EE bearded? The Lwlgbar pay be attacking to pluck those feathers. Not sure why she also attaches the other one.

Here is another article that might help you.

And yes if none of that works the Legbar probably needs to find a new home. Issues like this need to be solved with the health/happiness of the flock as a whole in mind.

One of the biggest reasons they attack one another is when one is ill.If either of the 2 hens are sneezing or showing other signs of illness it can trigger aggression from the others.

Edit:
In a previous post (a month ago) the Easter egger was very sick before the aggression began.Chickens are very good at hiding illness from us but its harder with the flock
.
"Easter egger was sick, we gave her medicine and she was almost at full strength when the legbar attacked her, we think to move up in the pecking order. Before we could get her to safety the Wyandotte attacked her too. The Easter egger had some bleeding and eye was closed. "
