i saved this in excel format. it is a spreadsheet i made by combining symptoms from different reference sources. it is not complete but a start towards a diagnostic database similar to what Ole MIss had posted. http://ompldr.org/vNXlxNQ/Poulty illness DRAFT.xls you can use "filter" tool to select and keep selecting symptoms until you get diseases narrowed down. not the best, but it is a start. Disclaimer: the better thing to do is become familiar with poultry illness/disease by reading links posted in "sticky posts." but it is just so hard to imagine disease symptoms w/o pictures or seeing the birds. EX: aspergillus is said to have symptom of "gasping" rather than labored breathing. ?.
