My hen was attacked by a dog.....she had a 5 inch cut under her wing which we sewed up and is healing well,. She stands and hops around and even jumps up and over things,,,but she is very unsteady, using her wings, and putting weight on the one leg. I checked out both legs and on the injured side, right at her hock...... the good side is smooth, but the injured side seems to have a depression. It's not swollen tho. Ideas?
