corn. thats it. my 5 week old chickens, they just go absoulutly insane for corn. like, they would sell their soul for corn. i made for them what i call "quarrentine corn-tea", and basically boil some water in a kettle, put some frozen sweet corn in a mug, and rinse it with the water, and drain. ive tried it before, it tastes fresh! then i take it to their run, and do the "here chickie chickie chickie" and the run right over. expecting nothing but corn. its crazy. its insane. ive learned if you have their favorite food, and hand feed it to chicks, they literally have such a trust with you, its wonderful. just.... corn!
