Ducklings attacked

[NesSyevans]

Hello,
Fox got in to pen last night. They are about 6/7 weeks.
Ones got puncher marks under both wings and Is very limp and panting.
Do you think I can help him? Or Is it cruel keeping him going??

If you want to keep him, sounds like a vet visit is in order otherwise I think I would lay the little fella to rest.
