Favorite hen has a hurt foot. Can you use antibiotics on a chicken?

Two days ago I noticed that my favorite hen, Little Girl, was limping. When her leg was examened I found some dried blood. Her leg doesn't look broken, dad and I both examined her. I washed her leg in soapy water. What kind of antibiotics can you use on a chicken's foot?

neosporin or any topical antibiotic ointment without the pain reliever. nothing with "-caine" in it.
