John, that is a section of fence line feed bunk under the guardrail and behind the panels/plywood where they usually get their gentling treat grain. This gets them used to coming into the corral. when I need them I just walk in the corral with the familiar white 5 gal pail of sweet feed.

If the vet is coming I get them in before he arrives. Or if I am running them through there is a time in the corral before I can get them thru the scale. I was surprised to find calves getting in the trough and being in a place they were not supposed to be so I put up the cattle panel behind the feed bunk.

I later found that cutting the sight lines through the panel and pipe gates kept them much calmer in the corral ahead of working or loading. I found some free 1/4" plywood that a lumber yard was throwing away and stuck sheets between the concrete bunk and the panel. Eliminates visual distractions and they stay much calmer. I also wired some of this free 1/4"plywood to the inside of several pipe gates for the same reason. Limiting sight lines/distractions is a Temple Grandin idea and works.

I usually work the group by myself so the calmer the better. Other than the small tray for the bull in another field so he remembers and keeps a taste for the sweet feed, and the calves for a time after weaning (trough picture above) the fence line bunks are the only place they get a bit of treat grain.
