I just have a question for everyone here,,,,,, If you're not willing to protect your live stock with the same diligence and force that you would protect your family, why do you even have 'em? To me, they're my children and I will do whatever I have to do to keep 'em safe from whatever threat they face. The same as I would protect my wife, my children and grandchildren. The same as I would protect you and yours if I see you in danger anywhere or anytime.
I didn't raise my family to be fodder for whatever dangers are out there, and I didn't raise my livestock to be fodder for wildlife or the neighbors dog. If you think it's OK for anything that comes along to kill one of your chickens off your boot-tops, YOU DON'T NEED TO RAISE CHICKENS. They depend on YOU to protect them, so protect them.
