I have 14 two week old chicks and I noticed a couple days ago that they were sneezing. I'd say all or most are sneezing and if I'm out there say 30 minutes, I might hear a dozen sneezes. The chicks are in an insulated garage, they are on non medicated chick feed/chick grit. I feed them mealworms/crickets as treats. They have poultry electrolytes in their water. They are in a cardboard brooder box with pine shavings/ground corncob bedding . They aren't showing any other symptoms, they are active, eating, drinking, pooing, etc etc. I do not notice any discharge from eyes, mouth, nose. I wasn't sure if I should do anything? Should I put ACV in the water instead of electrolytes? It's been going on about 3 days. Thanks!
