I was just asking about getting a used coop and what would be best to wash and disinfect it with, Guess I'll just wash it out with a hose and spray a little bleach mixed with water about to kill anything I don't my ladies catching.
best choice.... KISS.... Keep it simple.... Silly.
I am sorry to go on about it all. I am only reading occasionally and sometimes missing the original question.
