Today I noticed that my roo Indie was slightly less active than usual. He's pretty calm, so I didn't think much of it, but when I scooped him up out of the yard, he didn't fight to get away and this is a bird that isn't thrilled with being picked up. I held him for a minute, pet him and sat him down. He wandered away like usual. Tonight I went out to lock up the coop and double check that everyone was inside. I spotted him perched alone much lower than the other birds. He also didn't seem to be aware of how close I actually was to him. I got closer to check him out and noticed that his eye has some kind of injury. What would cause this and what can I do about it? Up close, it doesn't look like it's closed (I realize it looks that way in the pic). I will get a better one in the morning.
