I absolutely agree and will most certainly share the final report. I’m still scared I’ll lose the rest of my flock as I haven’t treated them with an antibiotic and not sure if a vet around here will prescribe one for me. Cornell is going to run some tests to see which antibiotic may work best. I’m also concerned as to where it came from, the vet at Cornell believes it was in their feed and that fermenting feed is not a good idea with chickens. She recommended that I switch gradually to a standard feed, no fancy grains, and throw the rest of the food out. How do I get rid of Listeria...are my dogs at risk....what about the soil? So many questions...
All good questions!
Ask Cornell if they will help with the vet - they may be able to call one in your area, tell about their findings and the vet will agree to write a script. Alternatively if you have good relationship with your dog's vet, send/take the report you get to them and ask for help - since you will be getting "official" information, I would hope they would work with you on getting this taken care of.
Since you have a very good resource (Cornell) ask a lot of questions

Pester them if you must - write down everything you can think of that you want to ask and see if they will give you answers.
I do not know much of anything about listeriosis - but would follow the directions that Cornell suggested. Get rid of the fermented feed and go about switching them to standard feed. My birds love wet feed, but I don't ferment. I make a fresh wet mash usually in the mornings - sometimes, I might make it the night before, but it does not ferment. My container that I mix it in is washed daily. Once a week I add poultry vitamins to my mash, a couple of times a week I may put in about 1tablespoon of ACV.
I try to make just enough for the day - I put out some in the morning, then sometime after lunch. You could try that to help your birds transition since they are used to wet feed - mixing a new wet feed everyday if you have time (I just put the feed in the container, add warm water and let it soak for about 30mins)
Dry feed is also available free choice.
I am so, so sorry you are having to go through all this.
I wish I had more answers for you, but I am learning from you. You have generously shared with us and I hope you continue to do so. Any information you get will be helpful to others that find themselves in your shoes.
