Some members of my flock seem to be falling ill My rooster (7yrs old) is very lethargic but still eating and drinking. Acting very droopy and sneezing. Foul smell coming from him. My first hen’s (7 yrs old) eyes have been occasionally swelling shut. Eating and drinking but also sneezing. Her symptoms were the first to appear and haven’t gotten better or worse. My second sick hen (6yrs old) is simply sneezing and has gurgling noises coming from her throat. I got some new chicks that were sneezing but also had coccidiosis (fully treated now), so I don’t know if there was any correlation. I don’t know if my chickens are just getting old (the younger hens in my flock seem unaffected) or if they are actually sick. I have been treating the flock with ocytetracycline. What should I be doing to help my flock? Thanks!
