Is there anything that I should do that would be part of a semi annual/annual deep clean on the coop, ignoring the issue of mites? If I'm replacing all of the shavings anyway, I may as well do a nice deep clean, because it's the right time of year (got the coop in November, so it's been ~8 months).
Every situation is different, and it might depends on your tolerance for poop stains, but.....
-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.
-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.
