I use pine needles or the long dried grass after I weed eat, because it's free and plentiful at my house. I was using pine chips but was going through it way too fast.
In the coop, I started with pine shavings. A friend recommended hemp (that's my "other"), and I did like that a lot. I wanted to put another bale of hemp on, but forgot to order it, so I got another bale of pine shavings. I forgot how nice those smell when they're new.
In the run, the chickens have a brand new patch of grass, because we just moved everything. I plan to let them munch that down, then add some leaves/straw/pine shavings from the coop.
What kind of bedding you use may depend on how you manage the manure.
This is about cleaning, but covers my big picture
-I use poop boards under roosts with thin(<1/2") layer of sand/PDZ mix, sifted daily(takes 5-10mins) into bucket going to friends compost.
-Scrape big or wet poops off roost and ramps as needed.
-Large flake pine shavings on coop floor, add some occasionally, totally changed out once or twice a year, old shavings added to run.
- My runs have semi-deep litter(cold composting), never clean anything out, just add smaller dry materials on occasion, add larger wood chippings as needed.
Aged ramial wood chippings are best IMO.
-Nests are bedded with straw, add some occasionally, change out if needed(broken egg).
There is no odor, unless a fresh cecal has been dropped and when I open the bucket to add more poop.
That's how I keep it 'clean', have not found any reason to clean 'deeper' in 7 years.
I use straw pellets, like they sell for horse bedding but smaller for chickens. The pellets break down pretty quick and become a soft sort of bedding. Soaks up all the smells and moisture really well. Haven't had to change it, I just add more.
