Contact you nearest AG Extension - I wish we had these
http://ucanr.org/ce.cfm
They will do your necropsy I believe and will also be aware of what is
happening in your area and be able to guide you to your most useful sources
of help
You have a very strong poultry industry in your state there is going to be
plenty of helpful resources. They will be informed and working with the
small flocks as these are both indicators and dangers to their own
Good luck
