You have gotten good advise so far.
I would trim back some of the feathers to keep them out of the wound. From the pictures it looks mostly like the skin and some tissue has been damaged and chewed up. I don’t see major muscle damage which is good.
Vetericyn and sugar are good. I used VCO and sugar too. Honey or medi-honey can be used. Due to location you may want to consider a slightly dryer wound care. Mostly so you don’t have sticky goo dripping off the chicken.
Keep us posted on what you try and how she’s doing. Pictures are always helpful.
