Hello, my new pig weaners made an awful mess using feed buckets before they got big enough to use the trough, and there is grower pig feed (20% protein) scattered everywhere. The pigs don't seem interested in what's on the ground. Can I kick them out to the pasture for a few hours and let my laying hens in there to clean up? I've heard conflicting things about whether or not hens can eat pig feed. Thanks!
