If it's just a minor cut or scratch it should heal quickly. If it's deeper it might take longer. How is he doing today?

He looks... Okay. Only that the seriousness doesn't go away. Above all that he looks like he's gonna make it

Hes eating

If he hit his head on something or was attacked by another bird he might have a headache, and that could be the reason for the seriousness. It's good that he's eating, and hopefully he'll be back to normal soon.

Does he live outdoors?

Coco is OKAY now, only thing though is his scar, he just went through his first molting (or however that's said) and I believe he's gonna have it for a long time until he changes feathers again.

Coco is living both inside and outside the house, and I know it might not be the best thing to do, but it's really cold right now, and I don't think he can stand this crazy weather, especially at night.

If any feathers got knocked out when he got the wound they should grow back in pretty quickly. I'm glad he's feeling better! Some outdoor time is good because exposure to sunlight is healthy for them. But you're protecting him from the extremes and that's good too.

Glad he's okay
