I have obtained chicks that had cocci and have been treated and are recovering if not already fully recovered. Can they ever be with my current flock? Will they possibly give my adults as well as chicks cocci? My flock has never had cocci and I have no idea if they would be immune or not or if even these little guys were treated and recovered can they transmit the cocci to my existing flock when it is time to have the chicks with the flock???
