I am utterly baffled, my chicks have started sneezing the past two days and I am baffled as to what is causing it. I give them electolytes and probiotics int heir water, change food and water daily, clean out water and feeder, spot clean brooder daily and am going to do a full clean tomorrow and change out all the shavings. I am using pine shavings and keeping them at 85*. They are a little over a week old. Like 1 week and 3 days old. They are eating, drinking, and active like they are healthy but still sneezing. My feed is medicated and I changed it out a few times wondering if the feed was too dusty but they are still sneezing. There is no discharge or wetness from their noses, just the sneezing. I am so baffled. Could it be my bedding? I also keep a little plate of grit with crushed mealworm and chick cake also called chick forage cake. I know the shavings get a little dusty but I have been wiping down the dust off the brooder with a warm damp cloth. My chicks are not sick are they?
