Our rooster Hei Hei was found four days ago with a really bad injury to his back. My husband believes a dog may have attacked him. I am not sure that he will survive his injury, but I have washed it out with iodine, diluted iodine, and I have put a Triple Antibiotic ointment inside and on the outside of the wound. I have also isolated him inside our house away from outlr hens and trimmed a few of the feathers laying across it. It is a pretty deep gash. On day four it still looks pretty bad. The inside has a yellow hue and there is a small spot of green. Also, it appears that he 1.) either has some severe caked up feathers -from dog saliva or blood or something?- Or 2.) Has a raunchy looking scab forming over the top. It looks like feathers, but my husband thinks I should leave it alone. He has some experience with birds, and fears I may cut a blood feather and him bleed to death. Anyway, if someone could show some pointers my way on what to possibly expect or if some of you that are more experienced more with chickens and these instances could tell me how you think it looks... if it looks infected etc. The first picture is today, and the second is the day I found him. Sorry you cant see the inside the wound very well on either picture. Thank you all.
