I would think with the distance, and freight, the tubs might be a better way for
@gcreekrch ... and I would be concerned that the cottonseed there might attract other animals that the tubs would not... what about the deer and elk and other ruminants that might develop a taste... yes, they can get into the tubs also, but we find that the deer here do not especially spend time much on the tubs....and then it might draw other predators .... and a bear or 2 would have a field day with those feeders... we have had a time with the bears tearing up 1,000 lb round bales just for fun at one place this year and taking the floats out of the water troughs, and the "saucer" type floats on the waterers that the cows push down.... I also realize that the bears should all be in hibernation.... but coyotes and wolves will follow the cattle if they congregate around a "feeder" ..... or other wildlife...
Just a thought on my part....
And I agree with them waiting at the gate for a supplement that they don't do with the tubs... we feed an all natural 16 % tub at the pasture with the heifers .... 1st calf and yet to be bred ones... just for some extra when the hay is not all the "best"... seems to keep them in better shape and they seem to settle down after getting their fill and not consume that much.
