Well, I handled him again and...The dent is gone. Lol. Interesting. Seemingly popped up over night, then vanished just as fast. That's crazy. I double checked to make sure he doesn't have any eye caps hanging around and he doesn't. Any chance he could've bumped his eye on something while trying to break the shed loose on his head? I'm grasping at straws here, but I'm curious to find out why it happened when the husbandry is spot on.
