Thanks again for looking into this. I have more knowledge too - funny how these things spur us to research things we've never looked at before, eh? I'm located in southern NH, for insect reference. :)
Ruminating upon this mystery as I tossed and turned in the middle of the night, I'm leaning towards the conclusion that the insects had nothing to do with Ballerina's death but were simply in her stomach when she died, given that the bugs weren't alive when she vomited them up. So that begs the question - what killed her?
Like everyone else who suddenly loses a chicken, it's frustrating when you have no answers. Did she have an impacted crop? Was she egg bound after all? Did she eat something that poisoned her? I know I have Marek's in my flock, but it doesn't kill that fast. Ugh, so frustrating.
The larvae were soft shelled, and I think that if anything had caught in her throat she would have been gasping immediately. That didn't set in until later. I was afraid that it was some sort of parasite, since she projectiled when she died and chickens don't barf.
That's a great idea about the farm bureau. I'll do that.
Thanks for your compassion - it helps take the edge off.
