The Cornish X I had was an excellent egg-layer and acted like a little puppy around us. She was an excellent pet. She laid very, very, very light beige eggs, 1 a day, sometimes 1 every other day. Her friends were 2 RSLs we got later. She had to have been 20 lbs or more. It sounds like your girl may have been egg-bound. I'm so sorry for your loss!
