In many parts of the U. S. people hunt from blinds over food plots that they have planted specifically for attracting and holding deer. Phillip and I both hunt in a part of Texas that does not receive the necessary amount of rainfall to grow food plots. I have asked several wildlife biologist including Dr. Kroll of the Whitetail Deer Institute at Stephen F. Austin University and they have all said protein feeders.
The ranch I hunt on in Throckmorton County Texas is 1600 acres. It is completely surrounded by other privately owned ranches. When I am there by myself I will spot and stalk but I don't hunt near boundary fences. When all 13 members of the family are there at Thanksgiving the only safe way to hunt is in our deer blinds overlooking feeders.
Thus the feeders function as food plots do in the rainy parts of the US. They allow us to evaluate the deer. They allow us to make proper shots on the deer. The deer fall dead long before they go onto another ranch. We know where every hunter is located and nobody will be shooting in the direction of anybody else. No one can leave the blind until 9:30am. We have visited with our neighbors and have worked with them so their blinds and feeders will not be shooting at our blinds and feeders.
Finally, please remember Texas of the 1950's had 500,000 whitetail deer. Today, our deer population is over 4,000,000. Texas has been at the leading edge of research in whitetail deer.
Your questions about Texas's hunting practices have been asked before. These questions have forced me to think about my actions as a hunter in Texas. This is my ethical response to your comments.
You are very much invited to come fix and fill feeders in July in Texas. I'll bring plenty of iced tea.
