My chick's wings went droopy and now she lays on her side all day.

[JoDucc]

She's a buff Orpington (one of seven) that Is a few months old at this point. Her weight is the same as all of her sisters and hasn't changed since these symptoms began.
She started walking around with her wings drooping and later began to sort of hobble as she walked.
I first noticed her behavior three days ago and have since separated her from the flock.
Thankfully no other birds are showing any sign of similar behavior.
There is no external trauma and her bone structure seems perfectly healthy.
I'm not sure if anything in specific caused the change. I first thought it may have been her just trying to weather out the hot days, but none of her sisters were behaving the same.
She's been eating and drinking scratch grains and regular chicken feed mixed with a little bit of chicken grower.
Her poop looks perfectly fine.
I've put her into a more temperate environment but haven't given her anything yet due to the lack of resources I have on hand.
I'd like to treat her myself as I do not have the spare cash to pay a bill from the vet.
They're in an old shed that I have renovated into a chicken coop. Currently they're separated from the older flock so they don't get terribly bullied as they grow.

She still has use of all of her limbs and can move them with quite a bit of energy if she needs to, so I'm not sure if it's just a point of her equilibrium being out of whack now. Any help or advice is appreciated. P.s. when held upright her head is seemingly always turned to the left.

(The first photo is from when I first saw her wings drooping, and the second is from today.)

Maybe a vitamin deficiency?

Please be more specific on the age as some diseases are age specific for onset of symptoms which are similar to the symptoms of heat exhaustion.

If it's been hot, it's not unusual for a single bird in the flock to become heat sick. First sign is imbalance, then stumbling, then paralysis. Give her one teaspoon sugar mixed into one cup water with a pinch of salt and baking soda added. Also, place cool compresses under her wings to bring her body temperature down. Never dunk a heat stressed chicken in cold water, though, as it will kill them.

@azygous @Eggcessive @Wyorp Rock

Perhaps? Would you happen to have any recommendations for vitamin supplements?

Though, I'm not sure how that would explain her lack of balance.

If I recall correctly her whole group is about 3 months old at this point.
The temps have cooled down significantly the past two days so I can't imagine that would still be an issue for her, but I will try getting her to drink that concoction.

 

[azygous]

Getting her to drink the concoction will help rule out or increase suspicion of an avian virus. Lymphoid leucosis has its onset of symptoms between three and five months.

If this is heat related, she should revive and return to normal in an hour or two.

Okay thank you very much. I'll get it to her!

Update: I fed her some of that water using a dropper and she's perked up quite a bit. If I support her upright she will chirp with a regular amount of energy and eat her food. She does not want to put pressure on her left leg if she can help it. There are no broken bones and she can still reflexively grip things if they're under her foot, but it seems like her leg is angled inward. I've given her a fan to help cool her down some more and will check on her as regularly as I can.

 

[azygous]

A fan only cools down humans who are capable of sweating. Chickens do not sweat so you have to cool down their blood supply when they are overheated. You do that by applying cold compresses (not ice) to the areas on their body where there are the largest concentration of blood capillaries - the wing pits and the breast.

Keep encouraging her to drink the sugar solution by providing it as her only source of water today. This will also raise her glucose levels and help restore her appetite.

If you suspect a leg injury, look for greenish bruising if her legs are white or yellow. Also examine the toes and foot pads.
