I discovered this morning that one of my chicks was not moving I thought he was dead but then saw him breathing but quite quickly he soon woke up after I gave him water but now he is just sleeping breathing fast and barley walking and when he does walk he walks slow and falls over. He is 2 days old and was perfectly healthy the other day running and eating fine. does anyone know what this is. I really don't want him to die. Also the bedding in the brooder in toilet paper for now I wanted to add the pine shavings when they were a week old because I thought they might eat the pine.
