I have not dealt with a deep wound or fly strike on a chicken either, but many of these deep wounds eventually granulate in with tissue. There are threads here with pictures of healing in stages. The main thing is to keep the wound clean using a mild cleaner such as saline or wound spray, and...
I really can’t answer that. If it were that simple, sour crop would not be so difficult to treat. @casportpony have you tried aspirating material from a sour crop, or flushing one and has it worked?
The injured chicken needs to be separated with food and water. Treat her for shock by offering some sugar water or electrolyte water up to her beak. Later wet chicken crumbles and egg can be offered. Saline can be used to clean the wounds, and antibiotic ointment or chlorhexidene cream may be...
It looks fowl pox a virus, spread by mosquitoes. It lasts about 3 weeks and most recover. I would flush the eyes with saline or eye wash. The apply some antibiotic ointment twice a day. Don’t disturb the scabs so you don’t spread the virus.
We cannot the video. I have seen hens walk backwards when they were molting. Sometimes it accompanies wry neck symptoms where they can walk in circles, backwards, or have a twisted neck up down or to the side. Vitamin E 400 IU along with 1/2 tablet of B complex, can sometimes help. To help her...
What is your general location in the world? Do you have any veterinarians where testing could be done? To me the lesions on the comb look like healing pecking injuries. They may appear black, then yellowish brown and later white. Have you checked the ears for any yellow discharge or checked the...
Is the feed dusty, or are there any environmental irritants that may be irritating the nostrils? Look for any debris blocking her nostrils. Has the chicken been near any new or sick birds. Any new members if the flock just added? Look for any bubbles or foam in one eye.
It will eventually fall off, but you could carefully trim some of the edges. Once all bleeding has stopped after a day or so, you could drip some saline or apply a warm wet compress to it for a couple of minutes and then remove it.
Do either of her hock joints look swollen? Mycoplasma synovitis can cause swollen ankles and hock joints. She could also have injured the foot. Can you place her back with her flock in her crate? It might be hard to reintegrate her back with her flock if she is kept away from them longer. Gout...
Do you see any bubbles in either eye or swelling around her eyes or her face? I would use a couple of drops of hydrogen peroxide into the ear canal, massage, and clean it out with QTips. Then apply a little plain Neosporin or generic ointment into the canal, daily.
You can also use Tiagard (Tiamulin, Denagard) to treat mycoplasma respiratory disease, and get it here:

Dosage is 2 ml per quart of water for 5 days.
Mycoplasma or MG is a chronic respiratory disease. Symptoms of...
You can upload a video to YouTube or a similar site, and that usually works. Make it public. It sounds like she could be dealing with a riboflavin deficiency, but Mareks or an injury could also be the problem. Do you have a rooster or cockerel or hens that could have injured her? Rooster Booster...
She probably has a respiratory infection, but just to be safe I would repeat the SafeGuard for a total of 5 days at 0.23 ml (1/4 ml) per pound, in case of gapeworm or capillary worms. Do you see any bubbles or foam in the eye on the side of the snotty nostril? Have you added any new birds recently?
Can you look inside her beak for any yellow material on the tongue or inside the cheek or roof of beak, that may be canker (trichamoniasis) infection? That can smell rotten and grow in size to block the throat and spread to the esophagus, crop, and sinus. Take a picture if you find anything. I...
Since the others have probably already been exposed to what she may have, I would tend to let her out with her flock so that there is less stress. When they are separated for more than a couple of days, they can be bullied when they come back into the flock. She sounds like she may have a...
You can give her a human calcium tablet with vitamin d3 orally, or break a Tums in half and pop it into her beak. That might help if she is trying to lay an egg. If you have any Corid you could try treating for possible coccidiosis. Dosage is 2 tsp of the liquid per gallon of water for 5 days...
