Go spray the yard down with "Hog In Heat". Use the hole dang bottle. You might get them breading faster than they thought hey could. You will have them so "happy" that they will be chasing cats, small dogs and squirrels around the yard to mate.
Great shooting, pics and story. Hey, keep that camera ready after spaying the yard down. You could start a new mag for the other hogs to draw them in. Hogler, Playhog or something like that.
Ok, I better stop. Im pushing my limits here.
