Identify this predator?

Prior to discovering the owl that was killing my birds, I couldn't find any place where a predator could have gotten in unless it flew in so up went a some game cameras. I do have video of the owl killing a bird.

Cmon, thanks for the photo. I lost my old male Ancona duck last night. The babies were locked in the house ,but he was out in the pen. The fence is 5-6 feet high. I found some feathers and a little bit of blood. My guess is an owl. I found no body or any other parts. I dont think a little fox could carry a 9lb. Duck and make it back over the fence and I’m not sure but I dont think hawks hunt at night. Pretty sure its not a raccoon cause they make such a mess and eat on the spot? Any thoughts or to anyone else who reads this? I’m going to put netting all over the top because I know they will be back.
