Do you have a picture of her droppings that show the tapeworm segments? Usually praziquantel is the best treatment for tapeworms. It is found in Equimax or Zimectrin Gold horse paste and also in Tapeworm tablets (Droncit or Drontal.) Equimax dosage is 0.16 ml given orally once and again after 14...
Be aware that aquasol only treats roundworms, not capillary, gapeworms, or tapeworms. The others I recommended will treat all except tapeworms. Aquasol is a weaker version of Safeguard meant for treatment in the water and has no egg withdrawal time. Dosage can be complicated, at least for me...
I wish I could tell you what that is, but it looks like pink mucoid poop or lining. In addition to the Corid, I would get some SafeGuard liquid goat wormer or the equine paste and give her 1/4 tsp orally every day for 5 days. Or you could use Valbazen or albendazole 1/4 ml orally once and again...
It does look like a peck eye injury. I would continue flushing the eye with saline and using either Terramycin or plain Neosporin triple antibiotic ointment 2-4 times daily for another week or two unless you can see a vet. She may be blind, but many chickens get around with sight in only one...
I would probably just continue the warm saline soaks daily or hold a warm wet saline compress on her rump while holding her. Then apply the antibiotic ointment until it heals. It looks like her belly is enlarged due to a reproductive disorder, and the others have pulled feathers and pecked her...
I would get acidified copper sulfate fro Murray McMurray Hatchery or from Jedds.com. It is very accurately mixed and dosage is simple—1/4 tsp per gallon of water. Use it for 3 days a month as a preventative or for 5-7 days for treatment of canker or sour crop. If your bird has canker of the beak...
She may have suffered some internal injuries, but hard to know without a vet. Do you feel any air pockets under her skin around her chest, side or neck? I would continue to offer food and water, and make sure that she is in a quiet environment.
Ivermectin is not approved for poultry, and if you use it there is no official withdrawal time. Ivermectin was found in the eggs for up to several months according to this study:

Are you using the Zimectrin for tapeworms, or have you confirmed worms. I...
Since her tail position is down and abnormal, I would give her 300 mg of human calcium citrate with vitamin d now in case she is having trouble passing an egg. Offer some fluids orally as well...
Very sorry for your loss. It would be worth getting the state vet lab to do testing and a necropsy. Keep the body cold/refrigerated. It sounds like she could have had colibacillosis (E.coli infection or other bacteria, such as mycoplasma G in her abdomen) causing egg yolk...
Valbazen, which is available now as albendazole 1/2 ml given orally once and repeated in 10 days is what I prefer. SafeGuard Liquid Goat Wormer or the Equine paste can be used 1.25 ml orally for 5 consecutive days and may be more easily found. Here is where to find albendazole...
