Excellent to have open eaves.@aart here are pictures of the eaves.
My husbands concern with this one is it is too close to the house. He was worried about the smell of chicken poop, and asked me to “check with the chicken people” if it will be a problem. As I mentioned before it’s about 20 feet from the house.
Tho it looks like some rot on the fascia, makes me wonder about the shingle condition and if maybe the shingles and fascia should have some repairs done.
Can cover the open soffits with 1/2"Hardware Cloth to keep critters out.
Several ways to do it, I did mine on the outside, see My Coop page.
If you keep it cleanish and choose the right bedding, it shouldn't stink.
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.
-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.
