I was looking at my neighbor's chicken coop, and noticed it was very open. It looked like a racoon could just walk on in! Since he'd been keeping the same chickens in the same coop for a long time, I asked him how he lost no birds. He said this. "If you pee on it every night, no 'coons ever go near it!" Well. Errrrr, so I guess if you are desperate...... personally, I've never tried it, but.... ya.
