I just came across your thread. I had the same thing happen to my buff orp rooster last fall. He was attacked by a dog. He didn't make it but I am so glad Holly is doing okay. I love this site because people know so much and are so much help to each other.
That's great news Spish!
When my hen was healing, I kept waiting for it to granulate in. I kept reading that you would see it slowly healing from the edges. But with my hen, the skin just started looking dryer and tougher all over, and then it started filling in with feathers.
That sunshine is really good for her! Don't know the answer about the skull. Time will tell. Alot of this is first-timing it for us!
You're a great chicken mama! Keep up the good work!
Thanks for posting spish as you can tell we've all been waiting.. Good to hear she's still healing inspite of set back. Tell her we're all pulling for her & you!!
