I'm sorry dh is blaming you. I could see one of my boys doing that very thing. You didn't do anything wrong.

He's just scared.
I think I would go out right now and get some heavy duty probiotic. I'm not sure what would be best for that particular bacteria but culturelle is widely available at drug stores and heavy duty and colonizes well. I'd give her a lot of that (as in
at least one capsule evening, one night--you can take the stuff out and give it mixed with cold food or straight on a spoon if she can't swallow capsules). I'd maybe even think of using p73 oregano oil (the p73 would be important). The oregano oil would be natural antibiotic though. If you wanted to do that you would maybe take culturelle morning, oregano oil mid-day, culturelle again a few hours after the oregano oil.
As the pp said, there is no guarantee that particular chicken had either bacteria. Camplyobactor would be the more likely. Both less likely if it was organic/antibiotic free. And even if it had it she might not get sick; that's why I would super do the probiotics. But the risk is there. Watch out for signs within the next 2-5 days--fever, diarrhea, vomitting, unwell..that sort of thing. I hope she stays well.

Go easy on yourself. This stuff happens.

I'd keep up with the probiotics for a while--maybe a couple of weeks--even if she seems well. I'd also take her in if she shows signs she is sick.
As you look for preventative things think about this as potential bacterial infection exposure. Might look into getting some florastor too in addition to the culturelle. I picked those two because they colonize and also they are effective against some really nasty bacterias--like c. diff. So would be good choices here too I imagine. I couldn't find particular strains for camplyobactor in a real quick search but you could look. I'd start her on probiotics this evening though.
