I noticed my silkie roo had some swelling above his eye last night around 9pm. He also had a small blood spot in the center of his comb (did not appear to have swelling there). I checked him again at 530 this morning and the swelling seems to be worse. The photo is from last night. I'm thinking maybe an injury from a run in with another member of my flock? Does anyone have advice on how to reduce the swelling/treat this??
