Well the photo looks blury to me so I can't tell, another is saying it looks like a little nip on the skin under the eye. I'll see if he posts the video. I'm sure if the chick was hurt she'd be comforting it and both look content now. She might have nicked it a bit, she's got a wicked beak.
Edit: Ok I think I see what they mean now, everyone but me saw it..go figure. There is what looks like a yellow blib on the side of the head..no blood or anything, nothing open like a cut. Not much we can do now as it's too dark to see anything
Waiting to see if he posts the recording.
