I'm back with the same chicken. Loss of appetite, mouth discharge. Frostbitten feet??

Photos of the yellow wattles?
Does she still have mucous inside the beak?

Look inside the beak for any yellow or white "gunk".

Tie her poof up or trim the feathers so she can see better.
Get her drinking - add some poultry vitamins or direct dose her with Poultry Nutri-Drench at 1cc per 3 pounds of weight.
Once she is drinking/hydrated, offer her some wet feed along with a treat of scrambled eggs.
Make grit available free choice.

The noise she is making sounds normal to me. Chickens make all sorts of noises.
I don't really see anything that odd about her head movements either, she is just looking around - maybe she's not able to see very well because of the feathers.
Hopefully @oldhenlikesdogs will chime in about the movements since she's had Polish chickens, she may see something that I'm not.

Poop for the most part looks pretty good from what I can see.

Definitely get her so she can see something by trimming a lot of tying those feathers back. If she can't see she will do lots of odd behaviors and can't find the food properly.

I've had several varieties of Polish. I really don't see anything that unusual. She may have a leg problem and I don't think that you are overthinking the limping thing. If they aren't walking right, they are usually limping.
I concur that you need to dose her with some poly-vi-sol or Nutri-Drench. Preferably the latter because it is formulated for poultry (not humans) and also contains some essential amino acids in addition to a complete range of vitamins and minerals.
I really don't believe you need to treat with Corid. Nothing I read indicated coccidia could be her problem and a 15 week old bird without specific symptoms would have become resistant long ago.
Now on to the urgent things. The malnutrition event sounds like it began when you were restricting feed. Some type of complete chicken feed should be available all day. Chickens are voracious eaters and will eat something. I'd rather that be feed.

Ventilation. You don't have nearly enough.
My buildings with peaked roofs have ridge vents the length of the building but they do nothing more than vent off some moisture.
If it were my building I would get out a saw and cut big holes in the walls stud to stud. You can make it look nice by trimming the holes out with some wood painted a contrasting color - that is, after you cover the openings with 1/2 inch hardware cloth.
The first building I built here is a gambrel roof garden shed repurposed as a chicken coop with a small window open year round and a ridge vent. But it isn't nearly enough so I built a shelf inside the window with a box fan on it and it blows directly toward one of the roosts - year round. Some of the chickens gather right in front of the fan even in freezing temperatures.
Bedding. As was said, lose the cedar immediately.
Pine shavings are much better.
Lose the hay as well. Hay will mold easily and can cause fungal issues. Both the cedar and any fungus will play hell with a tiny respiratory system without large quantities of fresh air moving through the building
Try to provide water in a regular poultry fount so it is less likely to be spilled.

Poultry drench is in, trimmed her feathers, provided grit. I forgot to mention the mucus stopped coming out, I haven't seen any today. The trimming made everything a lot better, which is weird because normal or not I've never seen that head ticking movement that severe before. And most importantly, SHE ATE. I'm sorry for everything being so disorganized.

It's strange, because I didn't know I was restricting feed. There's a inch and a half of food that's always in the bottom of their feeder that they don't touch for some reason, hungry or not. If I dump out the food unto the ground or something else, they eat it right up so it's not the food itself. I figure it's because it's too deep down for them to reach. After I really increased the food intake they were all going to bed with full crops, so I don't think I need to change the feeder quite yet.

The water is in a regular poultry fount. I isolated this sick chicken and so I gave her a bowl of water.

I'm working on the ventilation, I know this sounds like a bad excuse, but it's really hard for me to convince the rest of my family right now, and I know nothing about carpentry myself. It will get done, though, I promise that.

Glad to hear you got the feathers trimmed and that she ate!
Mucous in the beak can be from a lot of things - I suspect in this circumstance it was because she was dehydrated and not drinking/eating well.

Hopefully all will be better over the next few days as she is able to eat/drink.

I know you are doing what you can. Sometimes it's frustrating when family is not on board with projects. Maybe someone can help you with the ventilation and get that taken care of as well.

Please keep us posted.

You guys have all been so nice. Thank you. I was honestly a little worried about what kinda replies I was gonna get but obviously I've had no reason to worry at all. She's eating and drinking well, and back in with the flock because you're right I think it was just malnutrition again. She even went into the coop all by herself when before I always had to lift her in. The poor thing had feathers growing directly down over her eyes!

Still working on the ventilation. There's no smell of ammonia coming out of the coop at all and I haven't cleaned for a week. That's why I originally thought I didn't need more ventilation, but I guess no ammonia doesn't really mean anything?

No ammonia is definitely a good thing. The reason for better ventilation is so there's good air exchange. Without it carbon dioxide from respiration can build up, as well as moisture which can cause pneumonia.

Keep up on her crest maintenance. I find every time I trim my polish crests they immediately start growing out again so check her ability to see on a regular basis. She can't eat if she can't find the food.

Cedar shavings shouldn't be used, they can give off noxious fumes, I would remove them ASAP. Does she have a vaulted skull? Is her vision obscured? I will need to read your other thread to answer more.

X100 Never use cedar with chickens!

No ammonia smell is good. Stoop down around hen height and see how it smells.
Ammonia will come from high protein feed and high stocking density.
Other ventilation issues are (as previously mentioned) humidity, fungus, virus, bacteria and dust. All of which can flourish in a closed environment.

I'm so glad this place exists.

I think most every one here feels the same.
This place has more chicken knowledge now, than the Library of Alexandria had back then!
