I went out to feed and water and a couple of the young hens we let out everyday came running to me and around my feet and I noticed one had something hanging from its neck. It made another circle and it was its skin hanging with feathers still attatched and I can see the meat and all the goodies that lay under the skin. The open area is about 2 1/2 inches long and goes from nearly the right side of her neck to the entire left side. I'm guessing it was from that stray cat I saw last night. I have her in a small dog crate. This is what I suspect I have to do but wanted to ask the experts first. I first need to cut off the skin and feathers that is hanging and trim the feathers that are in tact out of the way of the open area and apply Neosporin to the wound. Keep her quiet and in the dark with plenty of food and water. I don't have any antibiotics except for pill form that I give my dog. They are TMP-S 960 mg. If I can cut or scrape some of it off the pill and maybe put on a treat or something I can do that if it is safe for her but I don't know how much. The pic is graphic so I have warned you in advance. Hope your not eating right now.
