I seen a few polled cattle get out just by using thier nose, lift their head and off exploring they go! A few of mine has done it.......and they were polled..
My point is you have a greater risks around horned cattle. Not with fences, but your and other (animals) safety. Cattle learn real quick how to use their "daggers" no matter how docile they are! Tehy can use it to bully other cattle from the feeders, or simply bully them. I seen/heard too many calves get injured by horned bulls during breeding season (unless the hrons are curled downward then the risk isn't so severe). I know most of you LH breeders are pretty bias and unwilling to know the facts about LH. Unless you have thousands of acres, I wouldn't be so trusty around your horned cattle by yourself or around other cattle. ANY animals can be dangerous, even your pet dog or cat. Horned animals is a greater risks to be around with...thank God dogs or cats do n't have horns.
