I seriously wouldn't go higher than the top of the fence...and be sure you have the toy far enough away from the fence to prevent escapes. Goats are very nimble when it comes to climbing and jumping and it seems that the higher they can get the happier they are.
I am hoping to get some giant rocks for them to play on. Also just got those big wood spool things. Hey do u have to cover to holes in the middle. I am worried their foot might get stuck. Love goat toys. They are so funny
yes cover the hole in the spools..they could step in it or get pushed by another goat into it & break a leg.
