It hurts when you get a hoof to the back or front!
as the case may be. grain seems to be like crack and my goats go nutso for it so there is constant beating banging and running around by everyone.. my way of at least somewhat minimizing this is filling the 7 plastic grain bowls before letting everyone get to me and the grain.. I then set 2 bowls down outside of the pen in the main aisle of my barn open the gate and stand to the side to avoid being trampled and then quickly take remaining grain bowls and scatter throughout the pen... then I goto filling hay bags.. this seems to work but still very chaotic and many a times I have been secondarily rammed by someone butting someone else into my legs.. constant vigilence and awareness is key!!!! I tried the plastic pipes cut in half and attatched the length of pen inside and then fill from outside of pen but what I found was there is nothing goat proof and they were constantly pooping, putting dirty feet or finding kids standing in them.. they also used them for rub posts and eventually they would break off or become so soiled I was constantly having to disinfect nightly before graining.. so I run the goat gauntlet nightly with my bowls of grain.. good luck in whatever plan you come up with!!!
