Can Salmonella be killed by antibiotics? Isn't that how they cure it in humans? It was my understanding that Salmonella can be transmitted through the egg shell, so are born with it in their system....so I don't know what to tell you about your chicks, except buy your child some kid size garden gloves for when she is around the birds and grab them off her hands before they hit her mouth.
Salmonella is a gram negative bacteria, there are several antibiotics which should kill it. In humans it's usually left to run its course: 4-7 days. Small children, elderly, & immunocompromised humans r treated w antibiotics.
So theoretically there will be quite a few of us (especially Pyxis) who will have chick-pics in approximately 21-26 days. Here's hoping there will be lots of chick-pic-sharing to see who hatched what from whose eggs.
