What killed my hen

[Ethannn]

We have this 1 hen and 1 rooster that we separate from the rest of the flock as they are more aggressive towards everyone, we left them out free ranging. The rooster stays close to the coop and forages around the coop but the hen got kidnapped as she likes to go in the trees and brushes. I can’t seem to find anything else but this any suspicions on to what killed her

dog or coyote maybe.
