My chicken was attacked by a dog. Below are pictures of her wound. I initially sprayed her wound with chlorhexadine, then I picked up Microcyn from Tractor Supply, sprayed that in there, and wrapped her wound with gauze and one of those bandages that sticks to itself. She's in a makeshift coop in my house separate from her sister. I'm also trying to give her 250mg cephalexin twice a day (she's 4.2lbs) and 50mg aspirin twice a day, along with electrolytes in her water. She is eating and drinking. Is there anything else I can do? The wound is really deep and in one spot (not pictured) actually goes through the thin layer of skin where her wing connects to her body. I know chickens are resilient but are odds good of her healing from such a severe wound?
