I showed chickens in FFA. That would be about the only real reason to bathe a chicken beyond illness or severe infestation. If I bathe one, I use dog shampoo, but you can use baby shampoo. White chickens are bathed in a solution of bluing water. Bluing is the stuff that used to be used for washing a long time ago because the faint color left behind makes your whites appear brighter and cleaner. I think it may also help take some of the yellowish tinge out of white birds. You can find bluing where you would get detergent and borax in the store.
(I had a white dog that I bought some bluing shampoo for once. I can't remember exactly who made it, but boy was she bright after a bath!)
Any time I've had to blow-dry a chicken, they really seem to like it. Even those who normally don't like me to mess with them will stand there and let me do it. You should use the lowest setting and constantly move it to avoid burning the delicate skin. (I'm sure if you've ever used a hairdryer, you know how hot it can get.)
