Hello there - Received 4 chicks yesterday afternoon. Have them nice and cozy in cardboard box under red heat lamp. thing is, I'm not a 100% confident on the difference between sleeping chicks and when they're sick. For instance, do baby chicks usually sleep standing or laying down on their tummies? one other question - since they're inside and under a red light, I'm not sure when to turn on the regular white light overhead in order to simulate "day" time. Is this even necessary? Thanks!
