I think I need to give my coop a massive scrub down. I feel like my girls are sick all the time even though we clean the coop out. Is there a good super cleaner or will bleach just work as well? How long do you have to keep the girls out of there for it to be ok for them to go back in? Pressure washing? Any help would be great! We tried the semi deep litter method but found that that just doesnt work.
