Actually they seem fine to me. I sold some chicks to a girl Thursday. We put them in a cage so we wouldnt have to chase them when she got here. 2 of them got sick acting so we took them out. They died on the way home to her house. She said they had air sac infections. I had no idea what she was talking about. She acted like I needed to treat the whole flock. They are all fine. They dont act sick or anything. I was afraid I missed something!! The 2 she took were either too hot or stressed. Thats what I think!!
