Well the old girls were moved out last week. I cleaned all the shavings out over the last few days. Tonight I spent a good deal of time on my hands and knees cleaning out corners, scraping off dried on poo, etc. It's not perfect, but 99.9% better than it was. I loaded the sprayer with 10% bleach solution and sprayed the crap out of everything. My question now is, how many times do I need to repeat it? I'm getting the chicks the 13th, so I don't really have a lot of time. Is once good enough?
