Goats ear bleeding. Predator?

[Rosetta]

I posted a couple weeks ago about my Nigerian Dwarf x Pygmy goat, Mario. His ear kept bleeding, and it was supposed his twin brother being housed with him, bit Mario on accident. Now there's a big dent on the tip of his ear and blood on the same side of his face. Could this be a small predator? Or maybe the scan opened up and took off a whole chunk of his ear?

I don’t think a predator did that. More probable that the scab came off.
