I've raised chickens in the past, but have not tried this method, so I cannot recommend it one way or the other.
The description of the method and possible benefits (less disease and easier maintenance) are given in enough detail to make it do-able.

The type of materials used for coop litter are also interesting and may have an effect on how well this works.
