In that first picture it looks like the side of his neck and body are pretty beat up. In the other pictures you can't really see it so well. It could be some scars left from fighting in the rut, but they don't look too fresh. In the last picture, I really don't think that all of those marks could come from fighting (especially that mark on his leg). He looks like a healthy deer, but his fur is kind of messed up. Maybe he just woke up from a nap and he was sleeping on his side
