When did this happen ? I had this happen to one of my old Ayam Cemani pullets. Hers was more sever though. Have you noticed any shaking of her head or not walking straight? I would say if you want to try and save her, then spay with veterciyn or the iodine water like you are and keep doing what you are doing. I’m glad to hear she is eating and drinking, as my baby would only drink and it was clear she wasn’t going to eat on her own again. Definitely use Neosporin with NO pain relief. It definitely helped my girl when I had her. As long as she’s eating and drinking on her own and you are keeping her separate with some good care I’m pretty sure she’ll be ok. Good luck and please keep us posted .
