I would use B complex 1/2 tablet daily. You could also in addition try some human vitamin E 400 IU daily which is used in combination with a small amount of egg for selenium and the B complex for neurological issues. I hope that she improves. Sometimes we do all we can do, and sometimes do not...
It looks more like your hen has some pecking injuries or has run into some wire fencing with her comb. That is not blackhead, which is a disease more common in turkeys.
If she has neurological issues or an injury to her back, I don’t know that a hobble would work, but use your own judgement. Here are some good ideas for a chickens sling in posts 5, and 11-14:

One of these might...
Casportpony has a lot of threads and expertise on tube feeding. I would say that as long as she is gaining some weight every day or two, you are moving in the right direction. I posted one of her ps in post 4, and here is another one with videos and and a lot of info...
Mercks vet manual says that 20 mg (200 mcg) daily is enough, 10 mg for chicks. But riboflavin and B complex is hard to overdose, since the excess is excreted by the kidneys.

Many people treat their own chickens and remove any yellow plaques blocking the throat and beak. It does tend to cause bleeding, so beware. Many people cull chickens with canker, since it is contagious to other chickens and birds. I have never treated it, but I don’t believe that it is ever...
What was she like the first 5 weeks of life? Did she walk normally, on her hocks, or have any issues? Do you think she may have been injured by another chicken or a jump with a bad landing? Poultry Cell has b2 riboflavin, but you could give her 1/4-1/2 tablet daily of human super B complex...
She looks like she has scraped her beak right beside her left nostril. Maybe she is poking her beak through some wire fencing, or on a feeder. The white chalky bit could be from healing skin. Look her over for any lice or mites around the face and under her vent and elsewhere. Have you seen any...
How long were the worms? Did you snap a picture of them? I am not a fan of the new Aquasol, since it only treats roundworms and cecal worms. It does not have an egg withdrawal time, which is good. But you never know if they are getting enough of a dose with something added to the water. The...
The PolyVisol will work for now since it has riboflavin, but the B complex is a better buy and goes a long way. Vitamin E along with a tiny amount of selenium is helpful with a neurological symptom, common in some leg problems. Too much selenium is not good.
She doesn’t look like a speckled sussex to me, but she could be a mix or another breed with a straight comb. I agree looking at her skin by parting feathers under her vent and belly and under wings, to look for mites, lice or their egg s is a good idea. Permethrin garden dust can treat either of...
Are you giving any human B complex? You can crush 1/2 tablet and add to her food daily, and that may help with her leg issues. General weakness or a vitamin B deficiency, can affect the legs, but time will tell (along with testing or a necropsy if you should lose her) if Mareks is an issue.
I would look at her eyes daily for any bubbles or foam, or any mucus from her nostrils, swelling on her face or around eyes, as well as frequent sneezing. Those are all signs of a respiratory disease which are contagious and can be lifelong in chickens. Her crop should be empty in the morning...
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...
