It is clearly stated stated in the TPWD website and says noting about counties.

A hunting license is required of any person, regardless of age, who hunts any animal or bird in this state, except as specified below. Non-residents under 17 years of age may purchase and hunt with the Special Resident Hunting License (Type 102).
[ul][*]A hunting license is not required to hunt the following:[*]Coyotes, if the coyotes are attacking, about to attack, or have recently attacked livestock, domestic animals, or fowl.[*]Depredating feral hogs, if a landowner (resident or non-resident) or landowner's agent or lessee is taking feral hogs causing depredation on the landowner's land.[*]Fur-bearing animals, if the hunter possesses a trapper's license or if the fur-bearing animals are causing depredation[/ul]
From another section on licenses.

A landowner on their own land or their authorized agent is not required to have a trapper's or hunting license if these nuisance animals are taken while causing loss or damage to agricultural crops, livestock, poultry, or personal property. However, such animals or their pelts may not be possessed or sold.


I will check with my wifes nephew who is aTPWD trapper to be sure. As far as getting a license, I will as soon as I establish residency. I will not pay 300 bucks to go shoot a few pigs.
