I tried roasting one of those mean ones last summer, you had to do a lot of sucking to get any nutrients once it came out of the oven. Actually I think it was mummified...
So the next time we murdered three more and stuck em in the freezer, well all but one, I got my nerve up to try soup this time. Into the pot it went, simmered and simmered and then we ate. I was still stringy and tough, and the darn thing was only about a year old!
So the third time, we harvested three more roosters and this time I looked up "how to cook a rooster" on google. Wow! seems I am not the only one ever having this problem, so I clicked on a site and the whole world of rooster pot pies and soup opened up right before my eyes! The trick is patience, you have to let the corpse sit in the fridge for a few days...To my surprise it worked!
Here's the site in case any one else is interested...

they also have rooster Coq au Vin and Corfu rooster along with Rooster pot pie yum, was it ever good!
Oh yeah, I put the stuff you don't eat into the black soldier fly "compound", saved the beautiful feathers and made a Fae headdress which sold the first day of the gallery show. Talk about recycling!
