I have a sickness in my flock... I first noticed it in one of my red golden peasants both eyes (area around) was very swollen and puffy actually eye lids matted shut. I culled the bird one red boiler had one eye swollen and I culled him. Some of the other birds were I guess you would say gaping? Kinda like gasping for air and seemed somewhat lethargic. I started administering antibiotics via water and two wet mash feeding a day. The next day the other red golden had a swollen eye so I culled him... I am guessing coryza? I am considering complete depopulization. My question is I also house pigeons with the chickens and peasants and none of them have had any symptoms with that said should I cull them also? This is seriously upsetting me as I have had birds for years and have never had any get sick... I cannot risk this moving into my closed aviary with my macaws and cockatoos please advise! Most of the chickens exhibit no symptoms either so I just don't know what to do... I have some bcm chicks in a separate area and have some more in the bator and I don't want them to get sick so experts help me!
