I heard a loud chirping earlier from the back porch. I knew that it was louder than normal. Hurried downstairs to find one of the Cornish Cross chicks had flown the coop. It was chirping really loud and looking around for the others. I thought I'd have trouble catching it, but walked right up to it and picked it up and put it back. Now there is a wire top on the tank they are in. They look like they have doubled in size since we brought them home on Sunday.
