So Rugby, Southam, and Warwick clubs had a grand total of 3 members sending this week as all the rest had some form of sickness. After two weeks racing. All clubs in our fed, keep there own crates, and do not not use another clubs crates. My own birds were off there food and not flying well midweek. Cider vinegar and honey was used in the water and yogurt on the corn. I spoke to another member on saturday and he had almost identical problem, though worse than mine. Surely this "virus?" must be air born? Any ideas.
