Just prepare it like a store bought chicken. I would not give him all that unless you feed your dogs a prey model diet and allow them to have 'gorge' days, otherwise you're going to have one unhappy puppy.
Pluck, gut, and give him pieces.. A whole chicken is a bit much.. I only feed organs like liver/heart and the gizzards to mine. I'm sure he could eat everything, but I'd wash the stomach and intestines first, unless you want him eating crap.
It happens, he's a dog, they're chickens.
I wouldn't give it back to him whole. To me, that seems kind of counter-productive if you want him to tolerate your chickens without thinking they're the food. My dog isn't allowed to attack our cat. If he killed one of them one day, I wouldn't have it back to him and let him go to town on it.
