I have wondered about the longevity. We get bitter cold and windy. I don’t know if the cold would make it brittle. I know it’s supposed to be rated for down to negative X degrees. But surely the cold will take a toll on it over time.
I have a mixed herd. Mostly quiet lazy broodmares who have a fair amount of self preservation. I’ve been tempted to do 3 flex rails with 2 hot poly strands for the foaling paddock. But really, why not just introduce the babies to the fence that they’ll live behind once weaned? So I may just do hot poly strands in the foaling paddock too and shut it off when they’re tiny; I don’t think I could take watching a day old baby hit an electric fence…
I do have yearlings through whatever age they finally sell at, so those can get a little goofy. But as it stands, they do get turned out with multi strand smooth wire and I think I’ve only ever had one hit it when they saw it at the last minute and turned on the brakes. So while they can get a little rowdy, they’re smart critters and will figure out that the fence bites.
