At first, I thought the WNV was confined to crows and jays as well. But here of late, there's been cases of blackbirds, cardinals, and mockingbirds being found dead in pretty large numbers. If this stuff affects the turkeys....well, I may just cry. As far as the testing goes, you'll have to come down to the house and try them for yourself! We're having grilled dove breast, fresh vegetables straight from the garden (peas, beans, squash, okra) and, of course, a big pan of hot homemade biscuits!
