Northern fowl mites lay eggs on the chicken's feathers. Do you see any of the adult mites? Look around the vent ans neck area. You can verify this for yourself by snagging a few mites and looking at them under a magnifying lens and counting the legs. If you see eight legs, your chicken has...
While we can't provide a firm diagnosis, we can point to several possibilities.
If her poop is normal, her problem doesn't particularly point to a bacterial infection. But you can try the Baytril if these other suggestions don't effect any improvement.
Just because she laid an egg doesn't...
The only thing that comes to mind is scaly leg mites. While the scales appear to be mostly healthy appearing, it's possible that mites are getting an early start in that particular spot.
To treat, you can soak the legs in warm water with a dash of Dawn detergent for fifteen minutes, dry and...
Is that poop from all of your chicks, or multiple photos of one poop from a single chick? If it's all from one chick, it's most likely harmless intestinal shed.
Coccidiosis would cause diarrhea and the chicks would act sick. And that intestinal shed would show up again and again, not just one...
In addition to what @Eggcessive has advised, in order to maximize the effectiveness of the Triple antibiotic ointment to treat a possible staph infection, bandage it. This is in addition to cleaning the wound each day with Hibiclens. You would probably need to only apply the ointment once a day...
As she kits out her gizzard with grit, she will be more eager for solid food. Make the choice available, and she will choose the solid food when she's ready. I would begin with boiled rice and cooked egg, or combine the two. Use poultry vitamins until she's back to eating her regular feed again.
Immobilizing the broken wing should make her feel less pain, but you can also give her one chewable aspirin two times a day to take care of the rest of the pain. Giving her electroyte water with extra sugar can help balance her chemistry that has been totally upset from the attack. Keep it up...
Doxycycline is an excellent med for respiratory illness but not really suitable for bacterial infection of wounds. Amoxycillin is far more effective. You can get it here. https://hardypaw.com/products/fix-mox-amoxicillin-capsules-fish-antibiotics?variant=44787640008865
We usually keep a wounded chicken separate from the flock while they heal so that the others won't peck the wounds and worse, attack the patient in their vulnerable state.
Veterycin is an excellent wound treatment, but for large wounds, it's necessary to use a product that will keep the tissue...
"According to research, Manuka honey contains more potent antibacterial activity than regular honey due to the presence of methylglyoxal. This antibacterial activity contributes to the medicinal properties that make it great for healing wounds, burns, coughs, colds, and other applications"...
Often when chicken keepers move a chicken into the house, they forget all about providing grit for digestion. Chickens usually pick up grit from their outdoor environment and we don't give it any real thought. Not being ablt to replenish the grit in her gizzard, her digestive system starts to...
She's a lucky one to have survived, even with a large wound. My guess is a hawk missed its target of her neck, usually breaking it, and strafed her back instead. I had a pullet once survive such a near miss.
You've gotten right on the wound treatment. Good job. Now, you must clean the wounds...
Don't you just love to experience the evolution of an idea? It pays not to be in a rush, and let the ideas unfold until you reach that point of inevitability.
What I was suggesting is not a flat joiner, but another arch at the peak, extending up from the outside walls. It would shed rain a lot...
I also live in the wild on considerable acreage. It's not much more tamed than it was when I moved here 31 years ago. I've been granted official permission by the district wildlife officer to kill any predator of my flock. But I prefer the "education" method over "elimination". It's effortless...
I know what you're up against because I've had more than my share of the treachery of bobcats. They are clever and they keep coming back.
I think you're on the right track with the idea of using bait. I also have hot wire around my coops and runs, and while the hot wire baited with peanut...
I think this could be an avian virus. This diagnosis is made all the stronger by the decline she's experiencing. The eyes fading may be another symptom of Marek's.
Are you in the US? What state? You should strongly consider having your nearest animal testing lab euthanize her and then do a...
