She can't be too short Victoria, her brother is pretty big in weight and height.
Plus,wethers are a bit different, in the way they carry weight, but may not look as beefy(well goatie) a chunky monkey, well darn, can't get the goat aspect right.
It is funny you should say, she likes standing up on things with the front hooves, well guess who else does that a lot too, LOL
My boers are always standing on the fence with their front legs. Maybe they like to feel taller. My nubians jump on top of everything. I have one that scales six bales high in my barn. Then she bounds down off bales to the floor just to repeat it again.
