I had a rooster attacked by a dog 6 weeks ago. His wounds were very bad and obvious, so I thought. He was so bad off I almost culled him, but he saved our hens so I figured he deserved a chance to fight for recovery. Even though his wounds were very visible, I found more wounds and some puncture marks two weeks later even after caring for him every day. Believe me I searched him for over 20 minutes for his wounds on the first initial check. I strongly suggest keep searching her for puncture marks. A puncture mark can leave no trace of blood. The reason I'm saying this is because if she has puncture wounds, she may need antibiotics. If she seems to get sick, not eat,and lethargic it may mean that she's getting an infection. If she starts getting those symptoms, I would give her antibiotics. I gave my rooster an injection shot of penicillin G procaine at 300,000 units per ml for 4 days. I gave him half a cc using a 3 ml syringe. If she seems fine and keeps eating, I wouldn't worry about it. She may just have a torn ligament which will just take time to heal. My rooster couldn't walk or put any weight on one of his legs for 2 weeks. He slowly has gotten better even his ginormous wound and puncture marks. He now walks, and will be spending his first night outside in the coop tonight. Happy new year to you all. Hope this helps in some way.
