Aw, Jules! I'm so sorry I'm just seeing this, now! Poor Griffin. I'm glad it appears as though he wasn't damaged as badly as he might've been.
As for his reluctance to eat, I remember when Bixby had injured his beak 2 years ago. The wider he had to open his beak the more painful it was for him. Oatmeal and baby food are obvious ways around this, but in case he's a bit more finicky than Bixby was, you can try focusing on smaller soft foods. Brown rice was a big hit, as it doesn't require the mouth to open wide, and it's soft enough not to require much chewing.
Also, feeding it to him through the side of his beak helped, as that part of the beak opens before the front. That way, he barely had to open his mouth at all. You could literally see his relief once I came up with that. (I don't know if Griffin is at the point where he'd allow that, but thought I'd throw it out there just in case.)
Please keep the updates coming, my friend.
