A few days ago, one of my young pekin-mix roos got sick. He keeps gasping for air and now, half his body feels bloated with air while the other half is skin and bones, even the leg doesn't have muscle. I don't know what this is or how it happened. A few weeks before this happened I went on a trip and left the chickens in the care of my older cousin, he doesn't know what happened either. I was hoping that someone would know what's wrong with him and how to help. We are currently giving him two siringes of electrolights. Anyone can help?
