Hi everyone! We just lost one of our hens the other day (she got really lethargic, had a cough/screech sound, and within two days she passed away). Now, our rooster Rufio has a similar siren/screech sound or cough, and we're trying to figure out if its a virus or a respiratory infection???? Just bleached and cleaned the whole coop, put down DE for any lice (had some in the summer), put some antibiotics in their water, etc. We move the rooster into our garage by a heat lamp so he can stay warm and try to heal. Any advice??? Or diagnosis??? Thank you!
