Thank you, that was interesting. Its hard to believe people raise them. The coop has been empty for a year, I'm not sure if that matters. We will definitely be wearing gloves and masks while cleaning it. We plan on pressure washing the inside, I'll probably use a couple gallons of bleach now that I read that! LOL.
Be careful! Bleach can mix with something in the urea and the fumes can kill. I grew up in NYC and pidgon poop removal is serious business for good reason. Who knew I was riding my daily commutes with walking poison poopers?!
