Hi, I have a Silkies rooster who is recovering from an attack. He has a nicely healing scab on his back that has been clean, dry and healing well with absolutely no sign of infection. Today I found his entire left side is swollen from breast bone to back bone and down his left leg. His right side is normal. It feels like a water balloon. He is walking, flapping his wings and crowing. I have no idea what it is or if it is related to his previous injury or not. I had some left over anti inflammatory drugs I gave him. Any thoughts would be appreciated.
