Help! I have a 2 year old asian black hen with a hurt leg.

Did you add electrolytes to the water? And the epson salt foot bath may help. Pictures of her leg would also help others give advice.
I always resort to electrolytes in water and rest may be her best bet, along with her best friend as support.

It's most likely a sprain or strain. Those take a week or sometimes two to heal. If you confine her so she isn't running around on that leg, it will heal more quickly.

You can give chewable 81 grain aspirin. Two whole tablets per day, stretched out.

When my duck had a hurt leg I gave her .11 mL of children’s Ibuprofen per pound of body weight.
