I keep thinking that. I may call tomorrow and just say they all died. I just want replacements ASAP. My little boys are sad. Our surviving chicken sleeps almost constantly - not sure if that is normal or if she's damaged from whatever happened to the other three.
Start them on sugar water but they do sleep a lot. They are babies. Let her rest, don't keep picking her up for a few day. A pet won't hurt though and an encouraging word.
