Yes bacitracin or plain Neosporin or Triple Antibiotic Ointment twice daily are good for wounds. Chlorhexidene (Hibiclens) and water or Vetericyn are good for cleaning the wound initially. What breeds are your chickens? She looks like a wyandotte. Those in my flock were the more aggressive chickens. Since they have pecked near her tail and vent, I would keep her separated in a wire dog crate with food and water for a day or two. BluKote can be applied to hide the wound when you add her back. But I would spend time with them to see what is happening. Do you have plenty of room for them, and are they getting outside into the yard to free range? Are you feeding 16-20% protein feed?
As for poops, I see a mushy normal one and a normal cecal poop. Is she doing okay today?
