Thank you for that Katy. That would not be good! Half of ours have horns, fairly simple horns. This is something we have to weigh up. We would train them to the fence closely at first. I don't know what is worse: half starving the whole herd by limiting them to fixed and insufficient permanent paddocks, or risking death by electrocution. The holes in the net are too small to fit a head through, but I could see how if they were eating near the base off the fence, then suddenly lifted their heads the horn might grab on to the net. If their horns had those loops in them, more spiral-like, then I could see they'd really struggle to get unhooked. Thanks for bringing that at up.
I wonder if there is a kind of shut-off system available which can detect if there is too many shocks happening like that. Probably not , because the system is designed to handle occasional shocks from grasses touching it often, right?
