I have one chick with her mother on a bed of shavings in a dog crate. My housemate, who frequently acts like he knows more than he really does, tells me that baby chicks will get confused between their food and shavings, and will die when they eat the shavings. Is this correct? If I don't use shavings, what should I use -straw? He also claims that chicks will eat straw, which doesn't even look possible since the chick's beak is far too small to even fit around a piece of straw.
