Ducks fighting? Help please!

Went to feed ducks (chucklings) this morning and found the ducks bloody.

doesn’t look like another duck, how predator proof is their pen?

They are in a kennel with chicken wire around it. Muscovy ducks.

Forgot to mention they are almost all like that.

Looking and acting better today. I think the problem was I had run out of duck food. Tractor supply was out, had to wait till the next day. Am I correct?
