The issue I have concerns with is the large flap of skin on the left side. I have edited the pics so you can better see the skin with the feathers in the first picture; and in the second picture, the flap is over my finger so you have an idea of its size. It is from the word "is" to the arrow.
The wound itself is healing well and I'm happy with the progress, but I didn't know what to do about the large flap of skin. It seems large to fall off or shrivel up, but also too large to try to remove...
I understand your concern now. So long as the wound is healing and doesn't become infected, don't worry about the flap of skin.
