Welcome to BYC. I assume that she is sick, and wasn't roughed up tl ause the swollen face. She could have a respiratory disease such as mycoplasma (MG.) That can cause sneezing, gurgling, nasal drainage, and swollen eyes and sinuses. Tylan 200 injectable from a feed store cattle section, would be good to treat her with. Use 1/4 ml or cc per 5 pounds weight, twice a day for 5 days. Give a shot or give it orally, keep her warm, and get her ro drink fluids. MG is very conagious to other poultry, and they become carriers for life.
