8-week old with balance / leg issues?

[gummunq]

We're new to chicken-keeping. We are keeping them completely indoors. One of them, about 8 weeks old, breed unknown (probably a mutt), has always been a bit clumsy. She (not 100% sure she is a she) used to be able to fly up and down to the roost (12"ish), but would often have crash landings. After a while she stopped trying to go up and down. Today she looks really unsteady, walking as little as possible, and when we hold her she has almost no ability to roost (she fell backwards off my hand :[... hardly flapped wings and didn't land gracefully at all). Comparing to our other chick who is same age but probably a cockerel, her legs are thicker and her knees bigger.... swollen maybe? Any idea what it could be? How can we help her recover quickly?

Note: We are in China and there are not feed stores or places to buy special chicken stuff that we know about. We would have language trouble communicating specific products anyway. I'm wondering if she is malnutritioned - we don't have grower feed or things like that, though our other chicken seems very healthy and energetic. We have been feeding them as a base: oats, millet, corn meal, and occasionally for treats: boiled eggs, crushed eggshells, salad scraps, worms, random fruits.

Hope someone has an answer out there. If you suggest some specific type of treatment or feed, we'll have to get creative and find the closest thing...

Does she walk OK on the ground?

Do you have Marek's disease in China?

With the lack of prepared feed, I'm guessing this might be a nutritional issue but I'm not sure what you'd be able to get - I imagine Save-A-Chick and poultry drench and all those other vitamin/electrolyte additives are not available. What do other folks around you raise their chickens on? The same mix of meal and scraps?

Wish I could be of more help - I'm pretty new too.

Thanks for the reply.
Actually she is walking around a liiittle bit today, but slowly. Maybe the leg emergency was a false alarm, but hopefully it won't be recurring. She's still really clumsy.
But for precaution, I would really like some advice on how to supplement nutrition. The only animal feeds I have found here are cat food and dog food. I think people don't go all out for their chickens here. People think we are weird, spoiling our chickens with such fancy variety like oats (haha). One of our friends raised her chickens solely on millet and maybe scraps. The best I can do for electrolytes is watered down gatorade. I wonder if they are low on protein and how best to boost. I don't really want to feed them meat.
I have no idea what breed they are but comparing to everyone else's photos of 8-week chickens, either they are bantam or they are underdeveloped.
