"...don't feel like cleaning 2 tonight"-Jeez, what a predicament!!

A few questions, if you don't mind as the only hog kills I've had are the ones I've raised fro meat.

Those were head shots?
Is it common for the other hogs to hang around after the shot? Also-you've got some bold turkeys there!

Are these baited or just foraging around?
Last-these are actually feral pigs?
I've been wanting to hunt some pork for a couple yrs now, I just don't know much about it. Got some family living in Alabama where I hear there are some good spots.
Anyway, good shooting & thanks for any info.
