We have three wethers and keep them in a five foot fence. They have never tried to climb the fences. That could be because we have climbing boxes for them They love to climb up on the boxes and climb into chairs to snooze. We feed our wethers medicated goat pellets I have never heard of feeding agoat horse feed. Although our horse sometimes shares his feed with Teddy one of our nigerian dwarfs. I don't encourage this as it can cause problems but when Teddy is determined he gets his head in there anyway. What kind of goats do you have that will determine what you should be feeding . A milking goat should not eat medicated feed etc. hope this helps Micki
