Chicken was attacked, puncture wounds

I'll try to get some pictures.
I have no syringes. We'll try to buy betadine anyway (good for all creatures of the household) if we have time. I don't think we have other antiseptics other than hydrogen peroxide.

Edit: It's just really strange, 2 chickens were clearly killed, but two were left completely unharmed.

If it is healing, I wouldn't use hydrogen peroxide.
That will kill new cells and delay healing. It works great when the wound is fresh. Like the first 3 or 4 hours.

Okay then, no hydrogen peroxide. It's definitely not a fresh wound.
