i came home for lunch from work and my barred rock is standing still in the doorway between the run and coop with her mouth open, making horrible bubbly croaking sounds. She has white areas around her beak, but may just be spittle? Also, I notice lots of diarrhea. She won't walk around or anything - definitely in severe distress. What can I do? Already put antibiotics in water, put NutriDrench on side of beak (won't swallow), and applied VetRX to nose openings. HELP!
