I have a speech tomorrow on Organic/natural vs conventional egg prod. idk what to say in it. I have 2 batches of brownies, one made with my eggs (all nat) and one with store eggs. im gonna have half the class take one and the other half take the other, then im gonna explain what goes into the battery hens feed. but what goes into their feed? and how do i explain battery hens, these are mostly non farmers.. and how can i "persuade" my class to eat organic, freerange eggs rather than the others?
