That is not the best series of photos to tell for sure, different times & only one at the bait at a time, the person who set the bait would know how far from the ground it was & what size the Hog was (looks like a smaller Pig ?) so they would know best ?
Looks to be a mature Hyena or Hyena's, too out of focus to line up the Spots to see if different animals
Id hate to shoot a lactating female feeding Pups myself but with the Spotted Hyena the Females are the largest, if in a group I normally target the front or lead animal, if I'm after a big skull, these don't normally have the best skins or fur, that's a younger animal with nice clean ears.
When I saw my first Spotted Hyena rug years ago, I was amazed at how plush the fur was, put you in mind of a nice Bear rug !
