I have a little 9 day old stinker in the brooder who is 3x louder than the other chicks...always has been. I just figured it was a loud breed or something (Silkie btw). Today it is peeping differently than it normally does. It's the same volume (loud), but it sounds like a pe-peep, pe-peep like it has the hiccups. Nothing is "wrong" with it (no sicknesses that I can tell anyway), no mites, no lice - no crop problems. It's eating, drinking, scratching and playing normally. Everything looks fine...and it's not doing anything 'weird' with its beak - its peep is just sort of "broken record/hiccup" sounding, as it's a half peep followed by a regular peep. Certainly roosters don't crow at 9 days old, do they?? Anything else it could be? (please say there's another reason).
