If you had a smell problem, then there was something wrong.
And if you were doing much work at all something was wrong.
Deep litter is just compost. It shouldn't smell. If it does, you don't have enough "browns." The only work involved is keeping it turned, and the chickens do that for me -- I just throw in a little scratch.
Also you need good ventilation. The more the better is my thought. Drafts are bad in winter but mine has a lot of ventilation and the window is usually open all winter to help with ventilation
