maybe he has an injury to the "jaw"...maybe out of alignment, popped out, or even broken..causing the swelling..
is he not able to peck at all?
are you able to go to a vet?
I'd give some aspirin..try and bring the swelling down..1 (325mg) tablet crushed into 1 gallon of water..
(some suggest stronger dose)
also try warm cloth pressed gently on area...
only use plain aspirin, nothing else.
maybe you can make up some soupy feed, and give by large syringe or dropper..
