I'm so sorry you lost a girl, this heat is just brutal. I would not eat it because you really don't know for sure what she passed from.Just went out to put ice bottles in the water buckets and found one of my hens had died, presumably from the heat. I thought they were all faring well with misters and wading pool.
It was one of my Bielefelders. They seemed to me to struggle more in the heat.
She had ants over her. It may seem crass but I assume it's safe to butcher and eat her?? Should she be refrigerated until the guys can do that?
