Yes, you can use it in a smaller area. How would you keep the pen clean? Or do they not have a pen (perhaps they free range and then are shut in the house at night)? What will be under the bedding--dirt, concrete, gravel? If it's gravel or concrete under the bedding, it won't decompose in quite the same way it will over dirt. Also, the fact that it's never rained on may have an impact, although if there is water in the shelter then it will certainly get plenty wet. I use DLM for my goats, too, and only in their shed, and I haven't had any problems there either. I do clean the goats out more often than the ducks, though, because their pee is stronger smelling and the bedding isn't decomposing the same way the outdoor bedding does for the ducks AND I have to put down a thicker layer and... well, it's just different than with the ducks, somehow.
I think lice are mostly a problem when other matters of management are neglected. As long as they have enough space, good nutrition, regular hygiene & maintenance, bathing water, etc., they should be fine. Or maybe I've just been lucky. Mine free range during the day and are locked in their pen only at night except when I am introducing new birds or have some other reason for keeping them confined over longer periods.
I don't use DE, but I'm planning to after my next visit to the feed store. I have heard so much good stuff about it. And we do have some flies and other undesireable critters, though never so far anything extreme. Still, I'm interested to see how much the DE helps. I'm especially hoping it will help me clean out the goat pen less often!
