ok mine has pale yellow to clear runny snot, coughs, sneezes ansd sometimes sticky eyes. i just sniffed my bird and it dont stink. maybe the reason eyes were shut is because of the snot gettin rubbed near eyes cuz i washed them and eyes look ok. normal poop until i started antibiotics. only affecting younger birds under 6 months old. older birds seem fine. they are eating and drinking fine, but sound hoarse and streatch neck out kinda like gasping. too many of the diseases have the same symptons. but my chickens eyes didnt swell like the pictures i have looked up. oh i have no clue. the more i research the more confused i get. could it still be corzya without the foul smell?
