Yes, I was going to pick up some of that tape just to make sure she sees it well. No it is not a TB, she is approx. 8-9 months old but she has been in a pasture with electric fencing before and she was fine with it and she is respectful of the fence(not going to say something wouldn't happen as it seems that horses are always gettting into some freak accidents).Flagging tape, hot pink or orange every so often so horse sees where fence is at is a good idea.
And if horse is TB? I would not do it as they do not do well with it, tend to get shocked, panic and run through it.
