I've used straw, but but shavings a week ago. With straw ($6 for a standard bale size), I could put my hen house 4 inches deep in the stuff, and repeat that process a couple of more times. With a smaller plastic-wrapped bale of shavings ($10 for 12 cubic ft), I use up the entire bale in my 8x10 hen house, only getting it around 2 inches deep.
I have no trouble scattering straw. I take a hard metal three-pronged garden claw (long handles) and easily push then pull back, thus turning it over. It fluffs up just fine. The negative to straw, as I see, is that a bird poops, and there it sits until you do your fluff up every few days.
The good part about shavings is that the bird poops, and it lands in shavings, which practically embraces the turd. It gets a protective shaving shell on it. The negative, other than it costing me nearly twice as much and getting much less of it, is that it loves to cling to the bottom of my shoes, and I track it all over the place!
Both smell nice. Both compost well, but beware: shavings are acidic.
As for clean up. It's as wash for me. With straw, I easily use to racks to grab large quantities. With shavings, you use a large shovel.
I'm going to return to straw when I buy more. The straw lasted me 5 weeks. The shavings will last around 2 weeks.
