Yesterday our speckled sussex rooster (a little over a year, under 10 lbs) was attacked by the neighbors dog. All of his tail feathers were almost ripped off, he had 2 puncture wounds above his left wing (not very deep, but a puncture). Some skin loss to his back side. We cleaned him up with soapy warm water, rinsed him off, applied some hydrogen peroxide and neosporin to the damaged areas. We've been keeping him isolated since the attack. His comb was purple a few hours after the attack, but turned back to red. He isn't able to jump up to perch (he'll fall if he tries), and is extremely lethargic. He can walk, and sit. He wasn't drinking water, so we force-fed him water with an eyedropper. He started to drink on his own and look a bit better, but his poop is nuclear green with black (mostly liquid), and now his right eye won't open. He's currently hiding in a make-shift towel shelter. We made a mash for him this morning but I don't believe he's been eating. I'm not sure if it's internal injuries, infection (bowels or respiratory). I was hoping someone could offer some words of advice. Thank you
