I noticed this morning that one of our 2 bardrock chicks keeps opening her mough and sneezes. Video: http://glovesandclover.com/temp/Sick-Bardrock-Chick.MOV (163 mb, give it a sec to load.) Any ideas as to what this could be or more importantly what I can do to help her? Sincerely, Concered Backyard Chicken Dad. P.S. Long time fan of backyardchicks website.
