My husband found our little bantam hen on the roost this morning looking like this. She had a small area of matted feathers on the side of her head that we cleaned up. We thought there was a wound underneath, but could only find swollen purple skin. She is in a lot of pain. We have put a baby aspirin in 1 cup of water and offering that to her. Is that the right dosage. She seems like she wants to eat, but it hurts to open her beak. She also has a sticky, semi-clear discharge from her nose. We noticed that when we were touching the side of her head, the discharge was increased. Can not find any obvious injury. Does anyone know what this might be? Possible bite? She was fine last night when I closed up the coop. Wednesday: She has been eating and drinking a little. She is still swollen this morning. Her wattles and neck look almost grey. She isn't super interested in food. I need to know what kind of antibiotics or what to give her. She kind of matches the symptoms of Coryza or Fowl Cholera. Yesterday she was oozing a pinkish discharge from her nostrils. This morning I had to clean out one of her nostrils because it was completely blocked with what looked like dry blood.
