We have two cochin chicks that are just a month old today. One is fine, but the other suddenly stopped eating or moving. She just stands or sits with her eyes closed. She'll drink a little, but otherwise just stands/sits there asleep. She'll let us pick her up without a struggle and periodically we'll find her beak-down and think she's dead. The local feed store is closed, so we made a Nutridrench-style solution with crushed multi-vitamins, water, and simple syrup. We dipped her beak into it about a dozen times to get a little in her, but there doesn't seem to be any change. What could she have?
