Oh...I did read that a female feral hog will birth a litter of up to 20...averages about 16 piglets....and she can do this up to 3 TIMES A YEAR! Now that's what I call recruitment! Also the reason they can get out of hand, as well the fact that they are supposed to be very intelligent and they wise up quick to hunting pressure. That nose is supposed to be as good or better than a deer. Maybe we could compare them to opportunistic black bears capable of recruiting sixty cubs per female each year. Could you imagine! As tough as bears are to hunt with that nose and a knack for avoiding hunters, if they reproduced like that we'd have a REAL problem on our hands! LOL
