Hi. My Silver Phoenix Rooster was attached a couple of days ago (Friday Morning) by a dog. He received a puncture wound on his back that looks really bad. It is not bleeding, but you can see his insides and it is kind of hollow-ish. I washed it out with sterile saline and someone told me to put this Blue Lotion from Farnam (contains ISO alcohol, propylene Glycol, Glycerine, Urea, Sodium Propionate, Technical Furfural, Methyl Violet and Acriflavin). The problem is, when i put it on him on Friday, it just kind of went in. And disapeared. So I quite using that, I hope it was not the wrong thing to use I will be very upset. And I used this stuff I used on one of my other chickens when she was injured last year called EMT gel that I bought at tractor supply. But her wound was just to her skin, it wasnt a hollow punchture wound like this. Anyways, I didn't stitch him up, maybe I should have, its probably too late now, right? Do I need to? I have attached pics so you can see what it looks like and help me make a decision on what to do. I started putting the EMT gel on him on Saturday and am still putting it on him 2x per day and again this morning. but it just seems to disappear in the hole. He is eating a little, and might be drinking, and every now and then tries to let out a crow (doesn't sound as good as usual). But he is mising a bit of feathers from his back and under his wing and I bet he is bruised pretty good from the dog getting him so he is certainly sore. Normally I can not pick him up, but he lets me without a major fuss right now. So, any advise? The first photo is so you can see where the wound is, and the second is a close-up of the hole and how you can see his insides and the slight hollowness, whatever i put on him disappears in his body after a while.
