got three pigeons at blackpool seemed no issue as I have had a good few over the years. two weeks ago a man came to see my pigeons he keeps pigeons on two sites , all types and breeds gets them everywhere . few days after his visit a yearling hen went bad ,got baytril from the vet and its ok now , yesterday a two year old cock died been ill as the hen was , I now have another two going the same way. when I phoned this guy he said his birds had been ill same symtoms as mine before I told him . I have had Baytril in the water since Wednesday , do you think he walked it in ?
