I'm one of those folks that doesn't use a dropping board, and am really happy with how our litter management is working out. We do deep litter - I started out with about 6 inches or so and haven't added any yet. We got our chickens at the end of February, so I haven't got lots of experience, but I can't imagine switching to dropping boards and having to scrape them daily. Our coop is a walk in 7'x8' coop and we've got 10 chickens. I turn the area under the roosts every other day or so. I keep a long handled cultivator in the coop and turning the bedding takes about 2 minutes. It might not work as well if you had a smaller raised coop, but for this size coop, it's been great so far.
When we built the coop we decided we'd try it without the dropping board, knowing that we could put them in later if we needed them. For me, morning chores consist of letting the ladies out to free range and checking food and water. Our pop door is automatic, so really, if I didn't want to let them out to free range, I wouldn't have to do anything in the morning. They've got a gravity feeder and waterer, so if I checked them at night, I'd feel comfortable not checking on them in the morning. That being said, I'd want to check on them in the morning, if only to say hello. I really love having chickens.
I guess my point is, you might want to consider trying your coop without the dropping board and if you're not happy with the way your litter management is working, putting one in later. The other option I've seen is building something box like under the roosts in which you put quite a bit of litter and then cleaning that out weekly. From what I've read, most people clean their boards daily, but the box thing doesn't require cleaning as frequently.
Good luck with your build!
