When my chickens were all sick they went nuts over a warm bowl of oatmeal every morning! Now that it's hotter outside they are loving me to bring them cold watermelon rinds. I just cut the watermelon in half and scoop the insides out with an ice cream scooper, making sure to leave some watermelon behing, and refrigerate the rinds. Once the temps. get into the 90's, usually around 2 or 3 in the afternoon, I take them the rinds. They go nuts! They also like cheerios, go nuts for cherry pie, chopped up spagetti, cantalope rinds, clover, worms, hard boiled eggs, cornbread with or without olive oil, kale, etc... The list goes on and on!
