I have some month old chicks in my brooder. It's a mix of Black Copper Marans and Ameraucanas all hatched together. I like to treat them almost every night with something little. I've been using whole kernel sweet corn or meal worms. Meal worm usually cause complete mayhem. They love them more than life. Both breeds dive in and get as many as they can. The sweet corn is a different matter. The Marans eat like they've been starving all day. I offer a hand full and then count my fingers when I pull my hand out. However, when I offer sweet corn to the Ameraucanas they come over look at it, cock their head and look at me like " you're kidding ... right?.... were are the worms?" They won't eat it! Just strange!!!!!
