Could someone please tell me about this disease? I got an email stating one of the chicks I sold was a carrier. I don't see how that is since the chick was hatched, was around other hatched chicks, was never outside or near my adult hens. Also, the chicks in with these were put outside over a month ago and no issues at all with my birds. No deaths, no illness, nothing to show a disease is present. It was stated they had several of their birds die from fowl cholera and one of my birds tested as a carrier. Would them being around the infected birds make them a carrier? How can a hatched chick be a carrier to a disease they were never exposed to at my house? Any info would be great!
