This is kinda crude and gives a rough idea how this part of the corral is set up. If you let the squeeze alley empty out a bit cows tend to walk right in, so there is seldom anything in the little holding pen at the back of it. When working calves we vaccinate in the alley and use a post to hold them in. No post is required when working cows into the chute.

Anyway, I'm sure there is nothing unusual about this setup, and I've seen it work very poorly when the volunteer help is not everything you hoped it would be. It works very well with good people who understand slower is faster.
