Pictures below of the space, which I beefed up yesterday after reading through a bunch of posts on this forum.
Chickens are just over a year old. I'm pretty sure the outcast is healthy, at least physically. Poop looks normal, no visible injuries. I wonder if they have fully recovered from their attack a month ago and are now restless, missing the ability to range freely like they used to. Their former favorite spots are now off limits.
The outcast has mostly been too stressed to lay. This am she wouldn't come out of the coop until the others had all left the permanent run. There are two bullies and the other two are fine with her, but choose to flock with the mean girls.
I think maybe I need to put the bullies in time-out, but where and how?? And what about bedtime? I'm not sure roosting is an issue. Chickens are so confusing!
Maybe looking at my set-up folks have some ideas? I'd put the bullies in the permanent run since it's smaller and not as exciting but then the others would be banned from the coop. Lock them inside the old fenced garden and put some food and water in there? Improvise an egg laying box?
Yesterday I added the sawhorse and pallet thing in the front and brought out the garden cart (behind compost bin). Coop with hardware-cloth enclosed 8x16 run on the right.
Old garden space, half fenced (open gates both ends), for dust-bathing, shade, etc.
Yesterday, based on what I read on this forum, I set up a second food and water station in this space and showed it to my outcast. (Here she is.) A non-mean girl came up and shared the water with her, then the other. I was hopeful, but today it's the same story of mean girls attacking and chasing.
