I've suffered from that in the past (9 dead birds in 2007) and it was utterly soul-destroying. I now have a strict cleaning regime (out with the Arklens on a regular basis!). I don't think FV is a problem this year - I saw one possible suspect chaffinch last year, but supposedly FV is a problem of mild wet winters. When the temperature's below freezing, it gets wiped out.

Salmonella and e-coli are a different matter...
