I am new to raising baby chicks. I lost one last night and have another that is puffed up today. I noticed that the chicks had poop stuck all over their butts so I cleaned their bottoms with a quip and warm water. Does anyone know why one of my chicks is puffed up? Any suggestions or help would be much appreciated. I bought them from tractor supply 2 days ago, the brooder is at a perfect temp iam feeding them non medicated starter crumble for chicks. Their poop is a brown color. Any suggestions? The puffed up chick is on the far right. Thank you!
