Not really possible to assess from pics. They have a LOT of ribs. Maybe some were damaged in that area. I wouldn’t be overly concerned, but I’d monitor.
I notice what looks like a slight dent in my corn's side. I first noticed it right before a shed, so I though it might be tightness from that, but we're post-shed now and it's still there. There haven't been any changes in behavior, and there's no bruised or damages scales at the spot, but I don't want to write it off in case it's something that needs to be addressed.
