I got a clip on fan and clipped it to the curtain rod on the window. It's drying out the floor right now (hopefully). It's well above the chicks fly hopping level so I don't have to worry about them trying to use it as a roost. Everyday I was opening the windows and it was fine but I missed one day and the ammonia smell was pretty bad so I got a small fan to help move the air out. Smells a lot better already.
