It might bother some people but the chickens definitely don't think twice...
I do not feed my chickens chicken but a raccoon killed 3 birds this winter and I pulled them out of the coop and set them in the run so I could use them for bait. A few other chickens came out and pulled out the food in the dead bird's open crop and started picking through it. They pecked at the dead birds decapitated head and were playing with the bloody feathers.
One time when I was a little kid one of the hens went missing and a few days later I saw the chickens running around fighting over another bird's foot. It came from the dead hen, they found her out there somewhere.
