I swear guineas have pocket watches and a nasty sense of humour! Every night at five o' clock they come flying and screeching from their house to the roof of my house. It's so sudden and loud, it stops my heart. I continue to feel the need to run outside and make sure no one is hurt. There I am standing in the yard looking up at these rotten guineas on the roof, and I swear, they're laughing at me! Right now, they're making the move to the deck where they will continue with their evil plan to remove the splines from my window screens.
