Luckily for George I was keeping an eye out, he'd been fighting with his brother a little earlier but I expected them to settle down as they'd done in the past but George was serious in his quest for dominance this time. He looked ok later after the fight was over but started acting odd (was in shock, I believe) and his eye started swelling shut so I got him out and give him a baby aspirin, once he perked back up I then started this thread to see what I needed to do for him.
I had some pure saline for scleral contact lenses so did much the same thing, used Neosporin and ordered Terramycin. Took about a month and a half or so before he was back to mostly normal.
George is back out with his brothers and everyone seems to be doing ok with each other. As the original instigator he's shown no sign of being interested in a rematch and none of the others appear to be interested bothering him. I suspect he's bottom rooster and if he's not seeing well out of that eye, will probably be content to stay there.
I do keep an eye on them, though.
