Sue, here is a quote from the article you posted. It was easy to miss this part. I added the part in red.
"The decision allows poultry producers to bring birds to state, district and county fairs in Wisconsin if they certify that they have not had a death on their farm within 10 days of the show.(Note - this applies to in-state residents only)
The decision also says that club or "open" shows and swap meets that may draw out-of-state birds will not be allowed through the end of the year."
End of quote.
