I did this once by just putting my hen in my left arm and using two left fingers to open her beak and popped it in. Some say pulling down on their wattles to open their beak doesn't hurt them and works too.
If it's warmer weather, how about giving him a bath, then take him outside with the blow drier on low. He'd lose a ton of his dander that way.
