My rooster had a recent eye injury/ infection which I treated him for and nursed him back to health, he healed very fast and went back into coop within a day or two after spending time in an isolation cage during treatment. I used vetricine, neosporin with pain relief and fluids and flushed his eye and it worked. He was doing pretty well and able to see out of both eyes but has always had a mobility issue (unstable on his feet) and unable to fly which is why when a visiting dog got inside my fully fenced yard (he slipped through the gate) and went into the chicken run and coop and went after any chickens he could catch, he got into the run because I left the gate open to round up my free ranging flock, for the night, as it was getting dark, I stepped away for a brief moment to check for chickens and heard a ruckus back at the coop so I came running to find the dog, I didnt really know what to do, I tried to scare the dog out, but he seemed confused and scared of me and instead of running out of 2 of the gates he ran straight into my chicken coop going after chickens left and right, panicked, I tried to approach the dog to command him to leave and I got close enough to try put him in pet carriers I had sitting there with 2 roosters inside, I let the roosters out, of each cage and carefully tried to coax the dog into the cage but it did not work and he tried to bite and attack me he bit my hand so afraid for my safety I grabbed my fishing net I use on a regular bases to capture misbehaving poultry and I wrangled him in the net as if he was a chicken. The first time I captured him he got out of the net but the second time I grabbed him he couldn't get away so I gently lowered him over the fence and into a separate fenced yard where he would remain contained and not able to get chickens. My part of the yard that my young puppy (german shepard) and my mothers dog (10 month old black lab) are normally in. They were not in there at the time. Or near me or the chickens and the puppy is being trained to herd chickens. So forget the dog. All I can think about is omg my chickens right. The rooster "Kevin" was huddled up at the base of a very large tree trying to hide from the dog, he was injured, with bite wounds all over that same side of his face head and neck as his eye was before. His feathers were everywhere on the ground. Also were feathers from my favorite hen on the ground. I informed my mother of what had happened, it was getting dark, 10 chickens roosted on the fence, 5 chickens, in two different spots, the flyers that flew to safety. The rest of the chicks were in the coop trying to hide from the dog. It was my worst nightmare. Everything was a blurry. Barley able to see in the dark I brought the chicken inside my house and wrapped him in a towel and laid him in my bathtub while I got him a hospital cage ready. My mother was banging and shouting because the dogs owner was leaving and she wanted me to speak to him. I didn't care about that right now, my main priority was to flush the bite marks and wounds on my rooster. I went out to quickly speak to him which he talked over me and denied and proclaimed innocence on the dogs behalf, I said I had a dying chicken to attend to and walked away didn't even give him the time of day and let my mother handle it. I flushed the wounds with warm water. I sprayed vetricine on the wounds. I applied neosporin with pain relief to every puncture wound I could see. And I wrapped him in a warm clean bath towel and put him in his hospital cage with some water. I fed him some banana and a slice of bread with oats and honey. I put a small heater on osolate blowing on him and covered his cage with a warm clean thick dry towel and I turned the light off and closed the door. He looked much better in the morning, I let him out of the cage and walk around inside the bathroom all day on some towels so he could "forage" for some various food scraps, feed, water, electrolytes and probiotics water, grass, herbs, greens, apple, bread, dirt, and sand from outside and a few grit pebbles mixed in his feed. He walked and pooped a lot. Poop was normal most of the day. I cleaned out his cage. Flushed his wounds. Applied vetricine and neosporin with pain relief to his wounds. Hes got some brushing on his back and neck, minor swelling on his face but no other injury that I can see. At first his breathing was funny I thought maybe his lungs and maybe some broken or fractured bones. But he didn't seem to be in too much pain. I gave him some fluids in a syringe and am letting him rest. I am hoping for a miracle.
