I like using a few Tbsp of treats to encourage my hens to return to the run when called. Just opened up a bag of Chicken Fun Doo today and I don't know what the heavenly chicken crack is in it, but my birds went nuts for it and were still scratching around for bits and pieces even after I finished cleaning up the run around them.
