I have a One-Week-Old Buff Orpington Chick that is growing well, and exhibiting no other different behaviors than the other Seven, but seems to "Yawn" silently, or "Gag" pretty frequently, maybe every Thirty Seconds or so, episodically. Accompanied with the Open Beak, Chick Elevates Her Beak in an up-and-down motion, with Neck extended. Is this normal behavior, or is it indicative of some disease or distress? Checked with Wilco, our supplier, and they say the chicks were NOT innoculated for anything..... Are we heading for trouble? Chicks have had Zero Outdoors, nor contact with anything but Me and My Wife.
