In southern Kansas they also use helicopters to eradicate the huge herds that can wipe out a entire crop overnight. My father in-law, who grows cotton in west Texas, also has had a lot of trouble with feral hogs in his fields. One thing he told me that I found amazing is that the average female feral hog reaches breeding age at approximately 7 months and over a five year period she can give birth to over 1,000 piglets.

Cheers,
