One of my six chicks are sneezing. it started when I put in new pine shaving and no paper towels underneath. the chicks were very interested that they could find the bottom of the brooder and are constantly making little holes in the pine shavings. The chick is not sneezing regularly. Only about once every 1-2 minutes. She is also sitting very fluffed up on top of my ecoglow 20. Could it be dust? will it harm her if I put electrolytes in the water even if she doesn't have respiratory problems? will the electrolytes hurt the other chicks? These are my first ever chicks. she is a buff orpington.
