Corid dosage is 2 tsp (10 ml) of the liquid Corid per gallon of water for 5 days. I would also worm the chickens orally with either albendazole (Valbazen) or SafeGuard Liquid Goat Wormer.
Yes, that does look and sound like canker, also called trichomoniasis, a protozoan disease carried by pigeons and other wild birds. It is extremely contagious. Your other chickens may already be exposed. The treatments that can be used include metronidazole (Flagyl,) ronidazole, and acidified...
How old is she? When one is paralyzed we tend to wonder about either an injury or Mareks disease. Mareks is a disease that can affect chickens in their first year especially. Does she have any curled under toes, or has she walked on her hocks?
How long has this been going on? Do you have any background on her illness? What state are you located in? I was looking back at your other thread. Are there any plants in the area or mold in food that could be toxic to chickens?
Here are aome links posted in another thread about ILT:

I don’t have any answers. I would wonder if she might have been pecked in the eye which could have caused the conjunctiva to swell. I would keep some Terramycin eye ointment, Vetericyn Eye Gel, or plain Neosporin on the eye twice daily.
I agree. It sounds like a possible reproductive problem. The calcium is a good idea. Make sure that she eats and drinks. You may want to observe her closely for the next couple of days to look for egg problems and to note her droppings. Post any pictures to help. Have you seen any soft or shell...
Shake the bottle well since it settles. Dosage is 0.23 ml or 1/4 ml per pound of weight of each chicken given orally for 5 consecutive days. Using a needle less syringe is a good thing for accurate dosage. That treats round, cecal, capillary, and gapeworms.
I have never seen ILT before. It is a contagious and a reportable disease in some states. Here are a couple of good articles about the disease to read:

I would update your other thread and post pictures of her poop. You can pop the softgel right into her beak. This is one of several videos on giving meds:
This year Terramycin became a prescription product. Jedds has sold it recently without an Rx. They may be sold out. I have used plain Neosorin or triple antibiotic ointment in a pinch. Polysporin is also available.
You might find it (Terramycin) here...
When I have had a stubborn broody out of the flock for a longer time, over a week, I let them go back and watch the behavior. There can be some chasing and pecking, but usually all goes well. If they need more time, a wire dog crate with food and water inside the run is good for a couple of...
