Hey all!! I bought some cream legbar chicks three weeks ago and the past 4 days I have had my oldest chick(5weeks old) start acting odd. Stretching out neck and gasping with no chirping. Checked her crop and looked for any obstructions. Nothing. This is day three of administering tetracycline per the advice of my local feed store. No improvement. Please help I don't want to lose her. I have given her 3ml of the medicated water every 1-2 hours. No change.
