Hi! I have a rooster (9 months old) who started with these symptoms: (1) droopy wings, (2) breathes with his mouth open, (3) his tail isn't up, and (4) he isn't crowing much. No nasal discharge, comb looks normal and his eyes are clear and bright. The weather is cool (November in New England). I have been giving electrolytes and using vetrx in the water. I have him some plain yogurt this morning. He is eating and drinking, and seemed to enjoy the yogurt. Is there anything else I should be doing?
