One more pic from last summer. For years I fed calves out in the pasture with the same troughs and it worked fine. This setup works much better with my work schedule though. I can easily spot one that needs to be watched and can count them really quick. When your dumping the feed you can pretty much look every calf in the face and see how their eyes and ears look. Down side is it takes twice as many troughs to feed same amount of calves. I plan on building one for the cows next.
Looks good. I've often wondered if you could just pound pipe posts close to a row a bunks of make your own "fenceline bunks." That confirms it.
My primary worry would be that they would try to sort and push feed outside the bunks, J bunks are offset to counter that, but if you have good feed it probably isn't an issue.
We have gone to 20' steel bunks. Glad to see the concrete ones go, the steels are way easier to move, clean, and hold more feed, less on the ground.
The concrete ones were okay if you were feeding pellets or grain, but didn't hold all that much roughage. We feed silage with a mixer, if you mound it up high they will sort and push and a lot of feed ends up on the ground.
I also broke a few of those concrete bunks flipping them over to dump the old feed out.
