Yesterday one of my hens was walking around with her tail feathers down and her shoulders a little up. She is a almost two year old BO, eating/drinking fine, pooping fine, talking fine, but did not seem interested in going out(unusual behavior)When I picked her up, I turned her over to check her out and when I writed her I heard what sounded like a little girrgle sound? I separated her for observation, she seems ok, lady at the feed store said to put garlic in her water, did that, any ideas what the tail feathers are a sign of, I have read it here before but can't remember. She did not lay yesterday or as of yet today. Thanks
