Thank you so much for the great information.W
What kind of wasp spray was it (i.e what was the active ingredient)? I did a little research on the subject and found that wasp spray is highly unlikely to cause death to chickens in a semi-sudden nature but is more of a concern when used around chickens long-term. However, it is still toxic and may cause illness to chickens when consumed. Because of this, I still highly advise using caution when you do use it... Many Backyard chicken owners present some non-toxic (absolutely safe for chickens) wasp killers/deterrents in this BYC thread: https://www.backyardchickens.com/threads/wasp-chicken-coop-help.478794/
You can read more about how most wasp sprays effect different animals (as well as the chemistry behind it) here: http://homeguides.sfgate.com/wasp-hornet-yellow-jacket-spray-also-kill-bees-97290.html
The berry-looking manure is the most concerning. Again, I am no expert and am not giving a diagnosis, just presenting theories.
Usually, when chickens eat enough black-berries to cause discolored droppings, you can see tiny, lightly colored seeds upon close examination (with the naked eye) in their droppings.
Cocci is an illness that can cause symptoms similar to what your chicken displayed from your description (then again, many illnesses can so I am not being definite here at all). Depending on the type and severity of coccidia, the illness can be sudden or chronic (slow). Necrotic Enteritis is another one... but I know very little about that illness in chickens specifically...

I hope this is helpful!and again... I am very sorry for the loss of your bird...
It is not a happy thing to lose one at all...
