one of my two week old chicks has somehow gotten a cut on her leg. it's about 3/4 of a centimeter long and is more of a slice-doesn't seem TOO deep and she doesn't seem to be having any trouble walking. not sure how it happened-nobody else is injured. I put some antibiotic ointment on it & it is no longer bleeding-is there anything else I should do for her? thanks for any suggestions!
