Yes definitely use the permethrin spray on the maggots now. I thought I had recommended that in my last post. Sorry I just looked and I had not said to use it yet. But yes use it now.
Try to control any flies in your coop with a fan, fly bait traps, and possibly using permethrin spray in the coop. Let is dry for 1 hour to let chickens on it, and it lasts a month.
Where exactly are the maggots? Can you bring her in away from flies? Can you get some permethrin spray to kill the maggots? If not rinse the maggots off in warm soapy water. This will need to be repeated for the next 24 hours. Do you have any pictures or a video that you can upload to YouTube or...
The Elector PSP is more for body mites and lice. Scaly leg mites are better treated with an oil to smother them 2-3 times a week, and ivermectin pour on. Here is some info on methods:

The Spurrs looks like alcohol, iodine, tea tree oil, menthol and eucalytis. It may burn, but it has some disinfectant. The Vetericyn may be more comfortable to use. I prefer using either Hibiclens or Betadine when a wing and toe are missing. The antibiotic ointment is fine. She probably is in...
Did you see any maggots on her vent or in the droppings? In the pictures there might be a faint something that looks like a maggot. Flystrike can be dangerous when there are flies out and a soiled vent. There looks to be some scaly leg mites. Castor oil, Vicks, petroleum jelly, or some sulfur...
Lice are more of a bother making them nervous and itchy. Mites could make her anemic and die. The Elector PSP should work. Your others should be checked and treated, and the coop, nest, and roosts as well. Recheck her at 10 days and retreat her, since the lice eggs will be hatching.
Have you added any new birds to your flock recently that came from another home? Swelling of the face can be from a few different things. First it is good to rule out a respiratory sinus infection, and look for bubbles or watery foam in an eye. An insect sting, injury or could also be possible...
The swelling can be around for awhile since you have probed and squeezed it. A lot of people keep thinking they didn’t get it all, and go back and keep messing with it. I have never had to go back again to open up a foot. Just put the dressing on it, and change it, but not too tight. She might...
Vetericyn is okay to use, but for wounds like those, I would get some Hibiclens or Equate First Aid Solution (generic Betadine 10%) and use one of those half strength on the wounds. Then apply plain Neosporin or triple antibiotic ointment twice daily. Watch for a bad odor or pus and redness...
Looking good. It looks to me like you got the infection out. Now just put some triple antibiotic ointment on it, and a 2x2, then wrap it, not too tight with a strip of vet wrap or tape.
It might be kind to her to cull if it is really bad this time. But soaking in warm water with Dawn or Epsom salts about 3 times over the next 24 hours, and removing as many as you see would be what I would do to try and save her. Get some permethrin spray at the feed store, or a product called...
