It's a natural behavior for dogs to kill chickens. It's also natural to chew up the house, poop and pee in the house, jump on people and a few other things that they aren't allowed to do. Killing chickens is just one more thing on the list.
How trained is your dog, really? Is she trained to respond to commands all the time, or just when not much is going on? Does she come when called? Does she come when called, when she's in the middle of chasing prey? Does she know commands like leave it or drop it?
I would work with her until she's reliably trained on all the important commands under any conditions, then work with her around the chickens.
How does she act around the chickens when you're out there with her, now? How do you react to her behavior?
We work with new dogs on a leash, to start. After they're good on a leash, we work with them on a long line. Eventually, we allow them off leash, supervised. It can take a long time before we test them while we're just inside the door of the house. It depends on the dog. If you have multiple dogs, then you have pack behavior to deal with. One dog can set the others off, so you have to be even more sure of their behavior. For a problem dog, I always work with them alone, until they're well trained.
A favorite thing for us is to also have the dog on leash while we sit on the patio and the chickens wander around, to acclimate them to the chickens.
You might want to lay heavy duty wire fencing on the ground around the run, to extend the no dig zone outward. I'd stake it down and also wire it to the base of the run. I'm wondering if the concrete band is just too narrow. You could also widen the concrete.
If you're unwilling to leave her in the house until you get this resolved, I would tie her. I don't think it's cruel to tie a dog temporarily. It's just a tool. The problem is when people have dogs living their entire lives tied out, with no interaction.
