Possible reasons for this difference includes a higher number of rural flocks in our study than in the WA and Boston studies (the Boston study was entirely urban). Wild birds, rodents, and mammals can all have <em>Salmonella<\/em>, and they can pass it on to backyard chickens, and our <em>Salmonella-<\/em>positive flocks have all been from rural farms\/homes.<\/li><li><span style=\"text-decoration: underline\">The good news:<\/span>  looking at by-bird rates, <em>Salmonella<\/em> is extremely rare in chickens in Vermont, with fewer than 1% of chickens testing positive<\/li><li><span style=\"text-decoration: underline\">Other good news:<\/span> In the flocks we tested, only one or two of the birds in each flock had <em>Salmonella<\/em> at the time we tested.
