Hiya all my chooks came with a very bad respitory infection which I cleared up with amoxicillin. It's been a week or more since they've been back to full health and off the medicine however this morning I heard the odd sneeze from one of my smaller chooks. Is it coming back so soon and should I start them on antibiotics again? Will my chickens always be ill, I can't keep getting the antibiotics every few weeks if this keeps coming back with this regularity plus they will likely get immune. Any ideas?
