Train him!
We started using meal worm treats to train our hens to let us pick them up. Think about dog training - it is very similar. Example: week 1, once a day, say "treats" and throw a few mealworms in the run and keep your distance. Week 2, once a day, say "treats" and stay kneeling down near them while they gobble them up. Week 3, once a day, say "treats" let them eat out of your hand. When we got to week three, I actually had a barred rock hen jump into my lap while I was sitting on the deck, minding my own business, eating an oatmeal cookie. No kidding.
My son can now walk up, calmly, to several of our chickens and pick them up. We make a point of not holding them very long, so that they know that we will not keep them captive - another point of training. Often, while holding them we will take the opportunity to check under their wings, vent, etc. and then set them down gently. This is a very practical benefit of this training - we can check their health without stressing them.
Also noteworthy: We used to chase them to catch them. I used to allow the kids to "play" with them. We thought this would tame them. It actually had the opposite effect and they were flighty and wouldn't lay eggs. We don't this anymore. They are more friendly and are laying eggs.
