Mine really love cooked corn on the cob, the bigger hens will try and pick the cob up and run away with it, it's really funny to watch. Occasionally, I also make a treat for them that is yogurt mixed up with cut up fruit and oat grains. That one is probably their favorite. Although it isn't necessarily healthy for them, every once in a while ill give them cooked spaghetti noodles mainly because its fun to watch them entertain themselves with chicken keep away. Any veggies that are still good, but not getting eaten we give them too. They love cucumber and the skins even.
