Yes, please post the results. Hopefully they can come to a conclusion.
Vinegar is acidic, which means it can dissolve metals. How was that stored? Did it perhaps absorb any heavy metals or create some other chemical compound that poisoned them?
You said everything else was the same. Did that include the waterer? Maybe a different “metal” waterer? I assume it was the same feed and feeder and was not moldy?
Vinegar being acidic should stop botulism from growing in there in case the container was air tight. I’m at a loss on this. It does point to that vinegar. Could you possibly send that along to get it checked?
Excellent idea.
