Just got off phone with penn state. They are going to check birds and they want a couple pounds of food.
This is a good thing...and if I may suggest, while things are still (unfortunately) fresh in your mind... you should sit down and write out a timeline of what happened.
Start with when and where you got the bag of food...find the receipt and make sure it is kept in a safe location.
Include when you fed the birds and how they were being housed at the time (include that you were careful to check for correct temperatures)
Then list the time you provided them the food and the time you first started seeing symptoms and how the situation progressed.
This may seem difficult and maybe not needed but if the 'wheels of business' move as slow as they are sometimes prone to do it will help in 2 weeks or 2 months to have it written down. I know you will never forget what happened but small details can become fuzzy in an amazingly short time.
