I probably give my girls tooooo many treats. They get treats usually twice a day--a protein treat in the morning (scrambled egg, steamed or raw fish, etc.) and a fruity treat in the afternoon (melons, grapes, peaches, sweet corn, tomatoes). They turned up their beaks at the pomegranate, tho, which totally surprised me.
We had a bag of wild bird food spill in the garage and rather than sweep it up, I called in the chickens to come get it. They ate all of it except for the sunflower seeds. I've tried giving them both the BOSS and regular type sunflower seeds, and they turn up their beaks at those, too.
Their FAVORITE treat, though, is when I'm about to pick up an old board or something in the yard that I KNOW has a million bugs beneath it, and I call the girls over before I lift the board.... I swear, they're like starving people at a buffet when that happens! It's hilarious to watch 'em scramble at the bugs!
