My flock is all sick! They are raspy, some have clear nasal discharge, coughing and noticed a rooster doing the silent crow like they showed for gape worms. I have been researching somethings. Totally confused! I have purchased some new birds but have isolated them but a few did get in with them one night. It started with one and then escalated into many within a couple of days. So my whole flock has been exposed. I currently as of today have the old flock locked in the coop together and have corid, Duramycin and safeguard mixed together in one water don't know if that is right or wrong but didn't think it would hurt. Hope I am not wrong. In the new coop I have the new ones and have a gallon water mixed wth the same 3 items in there waterer. Please help as I don't want to loose my whole flock. Also I forgot to mention my so. And husband have quail in separate Pena in separate buildings that the chickens free range around. Will the quail get this too??? I don't want them to lose them also??
