Hello @cdlord
I have ducks so my coop and run are a little different, but I do plan to make some modifications and add chickens. I personally use the deep litter method (DLM) and pea gravel in my run. I needed pea gravel around the ducks' pond. It was half and half but I found I preferred the DLM so expanded that part and now it is 3/4 DLM and 1/4 gravel. I just started in August of last year so I haven't had to do a full run clean out yet. I tried the DLM in my elevated coop but it didn't really catch so now I just have pine shavings and I scrap the top layer off each week into the run so it can start to break down. Then I add more shavings to the coop. The only time my run/coop smells is if one of my girls has just left a really sticky poo.
Otherwise it just smells like a compost pile, kind of a fresh earthy smell.
I will say that I did give them some straw in the winter to cuddle up in but I stopped giving that in December. I still have a lot of straw in the mix; it just doesn't break down as fast. Now I stick with mostly pine shavings. I did add leaves and grass clippings when they were available. I plan to use the litter in my garden this year so that's a bonus. It's also nice that I don't have to worry about filling my garbage with all the dirty litter.
