Ok did some checking on 20% range cubes. Bulk they are 16.5 cents a pound at 330.00T Ross seed in El Reno has them for 326.00T which makes them 16.3 cents a pound but there is a minimum of 500lbs if you buy them there. Atwoods has bagged for about 18 cents a pound. In comparison chicken feed, layer pellets, are about 28 cents a pound.
The cubes are large so they would have to be ran through a grinder or soaked up to use for chickens. I have a tag that I will scan and post later on this evening when I have more time. I want to have Carl look at the ingrediant list, some of the vitamins seem a bit high but there are few vits. that the body won't shed if there are too much brought in.
