On Saturday Suzie, a 7 month-old Speckled Sussex, was attached by a dog, a small area (2 sq.in.) of skin was ripped out but the skin was torn, creating an area of bare muscle a bit larger than the size of my palm. With help from a neighbor I trimmed feathers away from the wound, cleaned it with saline rinse, and disinfected it with betadine, sprayed it with polysporin and replaced it. I closed the wound with a sterile medical skin stapler, sprayed more polysporin, and covered the area with gauze bandage. The chicken was given tetracylin and electrolytes in its water. After overcoming the initial shock she began eating, pooping, and acting normally. I have changed the bandages and applied more polysporin daily. Now, 5 days later, she is still in good spirits but a small area of her wound has a light green tint. I don't know if this is gangrene and, if it is, I don't know how to proceed. What I cannot justify is spending over $100 on our overpriced vet so I need to continue with home care. Suzie does not appear to be suffering but I am prepared to have my neighbor cull her for me as a last resort. I welcome your advice.
