My dogs would be very upset with me if I didn't pluck - they get all that skin after the cockerel is cooked and bone broth is made in the Instant Pot.
I used to do it in a slow cooker, but IP is much quicker, easier cleanup, and makes the best bone broth!
The majority of my birds are around 5-6 months old at processing, but I recently had a 2 year old rooster and after 2 hours in the IP on Manual (the bone broth cook time), the meat was so tender, you'd never guess it came from an adult bird.
