I thought they said flu, but it was over a year ago. Maybe they just said disease survey. Nothing reportable ever found in my flock- we battle with the common lice and various other parasites. I know they went to three other places nearby, that also were as surprised as I, as it was not a prearranged visit. I did wonder if I was not home, would they have come onto the property. They caught about 15 of my 40 birds, they free range- and it was not easy. They even managed to corner one of the guineas. They were definitely doing throat swabs not cloacal. Now I wonder what they were actually looking for. If there is a next time, I will ask and be very specific.
