I've had Howard over 3 years and Billy one year both BFA. We adopted Koko a BG on the 30th of November. Since than Howard and Billy have had a GI infection. They were treated with baytril and metacam. Koko was tested no infection. They got over it and than Howard got it again. They are on the same food same routine the only thing that's changed is getting Koko. Our avian vet said stress can do that. We go back next week. Has anyone else had this happen? I feel sick if I caused this to them.
