THIS DAMP weather is KILLING my BIRDS suggestions?

[kelar]

I guess I have to ask if you are sure it is mold pathogens that are killing your birds? What you describe could be botulism or toxicity, but it could also be Marek's disease, which silkies are very susceptible to. Have any of the birds been sent out for necropsy? I also live in an extremely damp climate in the pacific northwest and even though the silkies have covered runs, the dampness is continually present in the soil through most of the year. In spite of this, I've never had, to my knowledge, a case of mold poisoning. Just a thought - so sorry for your losses.
