Chick with shaky legs

[SwartPeper]

I have a 7 week old chick (Silkie/EE cross) who was perfectly healthy until about 4 days ago when she started to get shaky legs. Each day it only got worse, yesterday she was struggling to stay upright. She will balance herself with her wings, and sometimes when she put her feet down she will almost close it, and lose balance. I have isolated her now from the rest. I really feel helpless, any advise will be greatly appreciated. Not a very good photo, but she is the one on the right:

Hi @SwartPeper

Shaky legs can be cause by a number of things - genetics, developmental or neurological disorders, vitamin/nutritional deficiencies and disease are a few things that come to mind.

What type of food are you feeding?
Is she pooping o.k. - what does that look like?
Can you take a fecal sample to your vet for testing of Coccidiosis?

Provide her with B and E vitamins along with a little chopped egg for Selenium. Try to keep her drinking. You can use a poultry vitamin like Poultry Cell or use human B-complex vitamins (no iron) added to her feed (1/2tab B-Complex and 1 Vitamin E capsule squeezed out) along with egg.

At her age, it's possible she may be suffering from a disease like Marek's, for which there is no cure. So ruling out other conditions like Coccidiosis and vitamin nutritional deficiencies is a good place to start.
